Dovecot
Hi,
i want to use dovecot as IMAP server.
but i don't get i
is use getmail to fetch pop3 mail. this works fine, but dovecut doesn't
the config is very complicated, the log doesn't say a lot and every howto on google says..."just install it and it works"
(every config i found looks complete different to the default config)
i want to use my linux accout for login. (the same i use for ssh oder the screen login)
can someone get me a hint how to config dovecot on arch? (there isn a wiki site available jet)
the wiki on dovecot.org is also very bad.
sry about this noob question but i spent days to get this working.
i don't think my requirments are so unusual.
(the first thing is just to get the login working)
thx!
@dontbugme
When you say it doesn't work, how exactly is that?
Have you tried checking the logs (/var/log/mail.log and /var/log/mail.err) for hints on why it doesn't work? How are you connecting to dovecot?
What howto's have you tried?
I have used the following (although my setup is with virtual users) to setup my mail server.

[SOLVED] Postfix smtpd exits when using dovecot SASL auth
I've been trying to configure my mail server with dovecot SASL authentication. I've been following the guide here to set this up. However, when I telnet to the server on port 25, I get this in the postfix logs:
Aug 4 21:51:00 localhost postfix/smtpd[2316]: connect from unknown[192.168.1.27]
Aug 4 21:51:00 localhost postfix/smtpd[2316]: fatal: no SASL authentication mechanisms
Aug 4 21:51:01 localhost postfix/master[2312]: warning: process /usr/lib/postfix/smtpd pid 2316 exit status 1
Aug 4 21:51:01 localhost postfix/master[2312]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling
After enabling debug logging in dovecot, I get this at the same time in the dovecot logs:
Aug 04 21:51:00 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth
Aug 04 21:51:00 auth: Debug: auth client connected (pid=0)

Is there any way to harden Dovecot against POP/IMAP denial of service attacks?
It doesn’t happen very often, but every so often a script kiddie on the Internet hits Dovecot's POP ports on our mail server hard enough to bring mail service to a crawl such that legit users can’t log in to retrieve their mail. I would say that with our 2.66GHz Intel Core 2 Duo Mac Mini Server, when we receive sustained POP login attacks that exceed ten logins per second, then eventually Dovecot gets swamped with so many requests that legit users are excluded. [Our server runs runs OS X Server 10.6.8-10K549, by the way, and Dovecot 1.1.2apple0.5 is installed as determined by running “dovecotd --version”. We keep the mail sever up to date with all available Apple software updates on a weekly basis, so we have the latest and greatest security updates.]
Here’s the problem: I’ve been studying the Dovecot 1.x Wiki at http://wiki1.dovecot.org/ and finding a number of parameters that *sort* of address this denial-of-service vulnerability, but none that appear to harden Dovecot in a similar fashion as ssh or sftp are hardened. By this, I mean that when ssh or sftp detect multiple login attempts originating from the same address above some threshold, then future login attempts are ignored for a solid fifteen minutes no matter what the login name was in the attempts. I’d like something similar for Dovecot.
I am aware of the “mail_max_userip_connections” setting which can be set independently for POP and IMAP service (see http://wiki1.dovecot.org/MainConfig?highlight=%28mail_max_userip_connections%29). This almost does what I want in that it indeed restricts the number of logins for a particular user coming from a single IP address. The problem is that the script kiddies typically scatter their attacks over hundreds of different login names and they may only attempt three or four logins per user name. What I really want is a parameter which starts to ignore logins no matter what the user name if too many come from a single IP address at the same time. Against this, I also need to balance my mail server restrictions to allow perhaps five or ten of my users with laptops to be behind a remote firewall, so all of their legit logins may hit my server perhaps three to ten at a time which could potentially look like an attack if my tuning parameter is set too low. What I’d really like to find is a tuning parameter that excludes concerted attacks without excluding my legitimate users. I also don’t want to invest in extremely expensive (>$10,000) “smart” firewalls that adaptively look for this type of attack, such as are offered by Netgear and other networking equipment manufacturers.
By examining /etc/dovecot/dovecot.conf on my mail server, it seems that Apple’s defaults are to set IMAP mail_max_userip_connections to 20, and for POP to leave the mail_max_userip_connections parameter commented out. Would there be any downside to enabling POP's mail_max_userip_connections to 20 as well? Offhand I can’t see how this would affect my users. Unfortunately, I also think that if I set the POP mail_max_userip_connections to 20 this won’t have any effect on the attackers since they typically won’t try 20 different passwords for the same login name in a given attack. I’ll post a segment of a log showing an actual attack that occurred today from the San Bernadino School District that I’ve since blocked in my network’s firewall, but it will illustrate the type of hard-core denial-of-service attack that I’m referring to. The login attempts were coming in fast, around forty-per-second, and my mail service went down in a matter of minutes as a result. [Yes: I will report this user… I haven’t gotten around to it yet with other issues.]
Any thoughts?Here’s a ten second snippet from my mail server's log, showing how intense the login frequency was from the attacker, and also how (s)he was "scattering" the login names used which I suspect would be quite hard to filter out using POP's mail_max_userip_connections parameter. The attack lasted from 1:43:39 through a server restart at 1:50:18, and even about a minute later. The attack stopped at 1:51:36 before I was able to add a firewalling rule to my router or to exclude logins from the 163.150/16 subnet from my router [FYI — that's the San Bernadino Country School District, according to http://whois.arin.net/rest/net/NET-163-150-0-0-1/pft ].
Any thoughts on how to block this type of POP attack in Dovecot?
[FYI — I changed my actual server name to 'myserver' and the actual admin name to 'Administrator'.]

Mail Server: problem configuring dovecot with postifx and virtualhosts
Hi all,
I'm am struggling trying to configure a mail server. I have a dedicated server running archlinux.
I want to setup a complete mail server, ie: web access (for that I installed roundcube) and being able to retrieve mails on any e-mail client.
I followed this guide, from the documentation but I've read that courier-imap is a lot more resources hungry than dovecot. As I could not have it working using the documentation, I tought I would use dovecot. The problem is that I am not able to configure it.
What I already have up and running: web server (nginx) with postfixadmin and roundcubemail, postfix, mysql.
Now, I want to be able to send and receive mails using dovecot. Could you guide me a little in order to replace courier-imap with dovecot, starting from this documentation? I already have my databases configured, a vmail user, ssl certificates and postifx configured for virtualhosts. Seems that the only thing missing is imap + smts thrue TLS.
Thanks for any help.

Error: Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory
error showing up, there is no auth-master file in /var/run/dovecot
this has just happnened over night
any ideas how to re-install dovecot
google search goes on about linux but barely any info about max osx serverauth-master is created when you start the mail service. Deleted if you stop the mail service. If that is not happening, you may have to re-install mail. Dovecot is the IMAP/POP part of the mail service. I am not sure what happens if you disable IMAP. I am guessing it is not there. But that is the extent of any tips I can offer. I suppose you could reinstall, but that seems a bit extreme to me.

Question about Mailserver and Dovecot policies
Hello Apple Cummunity members,
I'm currently installing a mac mini server for a client in the health sector. The installation and migration from 10.6 to 10.7 went smoothly but we hit a problem.
This healthcare bussiness has never used e-mailservice from a mac server but want to switch to mail services that are built into 10.7. The problem we are facing is about group-e-mail. We want to be able to use group e-mail like distribution groups in Exchange, and we don't want to use the built-in mailing-lists because we think they are not as user friendly as apple discribes. So we came up with a solution that utilizes server-side rules to forward e-mail from one e-mail adress to all the employees. The problem with this setup is that dovecot (mail managing) doesn't allow for more than four simultaneous forwards in server-side rules. I located the policy file in mountain lion server. But since we are using lion, this wasn't very usefull. I found a few lines that described the limitation to the amount of simultaneous forwards. But again, this was in mountain lion.
My questions are:
What version of dovecot does lion run on?
Is it possible for us to edit the policy configuration file from dovecot?
if so, where is this policy configuration file located in Mac OS X Lion?
Is there another soluciton in Mac OS X Lion Server to use a kind of distribution group-like feature?
I'm truly greatfull for all the help you guys can give me on this.
Kind regards,
Léon van de Broek
NetherlandsHi,
Agree with words of Samir, for more details you can refer the article “Understanding Authorization Policies for Remote Desktop Gateway”, might help in your case.

Duplicate messages and mixed up headers in message list from IMAP server dovecot 2-2.2.16
These may be two different problems, but they happen about the same time and resolution work arounds work for both.
1) My inbox occasionally fills up with duplicates of most (but not all) messages. There seems to be no rhyme or reason behind what gets duplicated. Once duplication starts, the messages that appear multiple times usually appear about the same number of repeats (1-5 repeats of each message) but not always exactly the same.
Weirdly, sometimes an incoming mail triggers a refresh that disappears the duplicate messages and everything goes back to normal for a while spontaneously.
I've tried Properties->Repair folder, manually deleting the .msf files, restarting TB, rebooting the computer, restarting the mail server, and changing mail directories. Restarting the server does nothing, the others sometimes but not always resolve the problem temporarily. (all the fixes I could find from similar problems posted by others).
It is quite annoying - not only does my inbox become unreadable, I don't know which instance to reply to.
I'm connected to the same account on the same server with K9 and have no such problems.
Problem 2: occasionally the header of a message in the list pane doesn't match the message in the preview pane. The above fixes resolve this problem to greater or lesser degree most of the time as well, but it always comes back.
Is there a problem between TB and Dovecot? are there any possible fixes?
I've been having this problem for a while: http://forums.mozillazine.org/viewtopic.php?f=39&t=2852813
Maybe has found a fix? I keep hoping an update will magically fix the problem, but so far no such luck.

[solved] dovecot errors after renewing SSL certificate
System:
OS X Server (Mountain Lion) 2.2
Using a single SSL Certificate for all services.
Symptom:
Users can't log into their IMAP accounts hosted on OS X Server (Mountain Lion) after renewing SSL Certificate
Diagnostics:
Give you an indication whether it's this problem. Some or all may apply:
Log shows all kinds of dovecot errors. e.g.
dovecotd[nnn]: master: Error: service(config): command startup failed, throttling
config: Fatal: Error in configuration file /Library/Server/Mail/Config/dovecot/dovecot.conf: ssl enabled, but ssl_cert not set
dovecotd[nnn]: master: Error: service(config): command startup failed, throttling
/Library/Server/Mail/Config/dovecot/conf.d/10-ssl.conf shows commented out lines:
ssl_cert
ssl_key
ssl_ca
Solution:
Go to the Certificates pane of the Server App and choose Secure Services Using: Custom
Set IMAP and POP server certificates to to None
Keep an eye on what the server App is doing to /Library/Server/Mail/Config/dovecot/conf.d/10-ssl.conf
Now set Secure Services Using: <My single SSL Certificate for all services>
Keep an eye on what the server App is doing to /Library/Server/Mail/Config/dovecot/conf.d/10-ssl.conf and you should now see all the ssl* settings as you would expect, and pointing to the correct SSL certificate in /etc/certificates
Hope this works for you too!I had something similar happen. When I do anything with SSL certificates it deletes any regular websites. Only the sites that are setup for https are listed.
Couldn't understand why my website wasn't working and it turned out that the system had deleted it. The web server had multiple host set and I had to rebuild all the ones that had used port 80. All the ones that use 443 were fine.
Hope this helps. -
Some incoming messages sent via dovecot are not arriving in inboxes
One of my clients has just found out that messages sent to her, from a specific sender were never received. The recipient has no rules set-up in Outlook, and looking at her account via IMAP/WebMail show no sign of the messages either. The SMTP log seems to show it getting processed and then the: delivered via dovecot service" message at the end of the process. But the message never shows up in my clients inbox. My client is a lawyer and right now she's worrying about other messages that may have not made their way into her inbox. I'm using SpamAssasin, ClamAV, spamhaus black lists, but everything in the log looks OK to me. is it possible that the sender is using an SMTP server other than the registered domain and that is causing the reverse lookup to reject it? I can't find anything in the logs to show that the messages are getting rejected at some point along the way. And they're not sitting in the Que waiting to be distributed. i'm stumped.

Move 10.6.8 Dovecot to clean server setup 3.1.2
Hi All,
I am planing to do a clean Server.app 3.1.2 on 10.9.3 setup. I currently have a 10.6.8 Server running e-mail. Both are Dovecot but when I setup new Users on 10.9.3 they will have new GUID. The Dovecot mail directories will not match without some manual labor.
Any ideas or suggestions on how to tackle this would be helpful.
Thank you in advance.Thank You bobaloo2,
Sounds like a solid way to go. Just curious with the "Export your users and groups from Snow Leopard Server" and import into Mavericks server will I still have the Schema errors I have under 10.6.8?
Since I migrated each server update starting 10.3 to 10.4 then jump to 10.6.8 I noticed some fields give me errors when I try to enter them. I was informed this was a Schema issues but I should not worry to much. (i.e. Under WGM fill user "info" fields in like "Company, JobTitle, Department") These field where added later in the server builds but even when I create brand new users under 10.6.8 I can not add to these fields since to the best of my understanding the migration imported the old Schema as well as other related Open directory data.
I will try the move and CLI perm on the Mail and post back my results. -
Note: Mail.app and Folders with Dovecot - Copying Folders w Subfolders
I found a problem with Apple Mail regarding folder creation with the new Dovecot Server...
Say you import some mail from Eudora or some other mail client, and you have folders with no messages, only subfolders (or mailboxes if you want to call them that). The mailbox on "My Mac" appears white instead of blue, and you can see the subfolders just fine and everything looks great. Drag that folder (the white one with subfolders) to your IMAP account to copy it to the server. It will copy just fine. Now try to rename or delete that white folder you just copied to the server. You will get the following error:
For this example I will call the problem folder "TestFolder"
The IMAP command RENAME (or DELETE if you try to delete) (to TestFolder) failed with the server error: Mailbox does not exist: TestFolder
The problem is this:
Dovecot creates folders and subfolders as separate directories on the server:
.TestFolder
.TestFolder.TestSubFolder1
.TestFolder.TestSubFolder2
In the above example, there is a folder (or mailbox) called TestFolder with two folders inside it, TestSubFolder1, and TestSubFolder2. This example is the correct way to create a folder with dovecot, or if not "correct", at least you can delete or rename the "TestFolder" without an error.
What happens with Apple Mail (Mail.app), is that when you drag a white folder to the server, it would create the following:
.TestFolder.TestSubFolder1
.TestFolder.TestSubFolder2
Notice the root folder .TestFolder is missing. This is why you get the error message noted above. If you create .TestFolder in the directory, chmod 700 .TestFolder and chown <username> .TestFolder, you can rename or delete the problem folder (notice it turns blue as well). This gets rather annoying when dealing with multiple folders/subfolders, and is not a real graceful way of dealing with the situation.
Apparently there is some intended difference with the white folders and blue folders, in that blue folders can contain messages but white folders can only contain other folders. Great, but Mail.app needs to somehow create the folder on the server in a way that is compatible with Dovecot.
If someone has a developer account (mine keeps complaining that there is missing information, but there is no missing information and won't let me log in), could you post this as a bug report? I'll deal with my developer account later...
Thanks.> It's not that they don't show up in Mail. In Mail, they are in their
(manually) sorted folders. On the server they are in BOTH their
sorted folder, AND the main inbox where they first appeared.
Yes, but what I’m saying is that, according to your reports, even after rebuilding the Inbox of the .Mac account that has the problem, there are still messages in that mailbox on the server that don’t show up in Mail in that same mailbox. Is that correct? This is what doesn’t make sense to me...
> Mac-mydotmacusername1
Mac-mydotmacusername2
[email protected]
So you have two .Mac accounts and a POP account. You hadn’t mentioned this before, had you? I got the impression that you only had one .Mac account...
Which account has the problem, i.e. for which account there are messages on the server’s Inbox that don’t show up in Mail even after rebuilding that mailbox? Are you moving messages from a .Mac account’s Inbox to custom mailboxes of that same account or to mailboxes associated with the other .Mac account?
<hr>
Try this to determine the scope of the problem:
1. Go to Apple Menu > System Preferences > Accounts and create a new user account for testing purposes.
2. Either log out of your main user account or just quit Mail so that it does not interfere with the other user account.
3. Log in as the newly created user and set up Mail anew there.
4. For spam-related security reasons, go to Preferences > Viewing and disable Display remote images in HTML messages if it’s enabled.
5. If you set up a POP account, go to Preferences > Accounts > Advanced and disable Remove copy from server after retrieving a message if it’s enabled, to avoid messages being accidentally removed from the server while testing.
6. Check whether the problem also happens when logged in as another user. -
I tried to set up a mailserver on my server, and it is possible to recieve mails normally. Strangely, whenever I connect to my server via a mailclient, it does not seem to get any emails, nor can I send any. The error message
May 25 15:47:37 thunderserver sm-mta[14374]: r4PDeNDN014241: SYSERR(root): Cannot exec /usr/bin/procmail: No such file or directory
makes me scratch my head. procmail is intalled, has a barebone config, and the file does exist. I triple checked it. Where could be the issue that 1. the mailclient cannot get mails from my server 2. cannot send any?

How do I stop/disable/remove dovecot and postfix?
Hello,
So the story is somehow I managed to install Lion Server on my personal computer from the App Store. Fine until I realized all the proccesses my computer is spending resources on now. I've looked through what I think is every guide in the book on how to "remove" Lion Server, meaning just disable the additional servers it installs. I think I've gotten almost all of it, following basic things such as shutting everything "off" in Server.app.
Seems that though, no matter what Launch daemons or agents I disable, two are persistent on starting up with my comptuer and I can't seem to rid myself of them. Yes, I need to stop/disable/remove them. The following shows up in Console.app > All Messages:
Dovecot (or something related):
1/24/12 10:57:58.490 PM dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: No such file or directory
1/24/12 10:57:58.491 PM dovecot: lda: Fatal: Internal error occurred. Refer to server log for more information.
Postfix:
1/24/12 10:57:58.105 PM postfix/master: master exit time has arrived
1/24/12 10:57:58.143 PM postfix/master: daemon started -- version 2.8.4, configuration /etc/postfix

I believe both of these are related to mail somehow. I have ticked off "Mail" switch box in Server.app.
These messages keep on looping in the Console since I'm assuming they are crashing and then restarting due to a "stay alive" in some plist file I can't seem to find...
Please, I would be very grateful to anyone who can help me unclutter my Console of these messages. I know I can filter senders, but I will like to see if I might get some advice to resolve this. I'm sure it's minimal, but it can't be good for battery life. I wish I had the time to do a fresh install of the client.
Cheers!
RyanI have the exact same problem, and I'd appreciate a response. My logs are flooded by nonsense!

How: poll POP3 from ISP and feed into OSX mail server (Dovecot)
Hi all,
My desire: use IMAP for all my iOS and OSX devices to forget about the synchronization nightmare when using POP.
My ISP only provides POP3, and I can fetch emails from his POP3 server so they end up in my mail client on any OSX workstation.
But I want to use IMAP via the Dovecot email server on OSX server mountain lion.
How do I implement that missing link?
Can this be done by a cron script, mimicking a MTA?
Somehow the OSX mailserver cannot be convinced to fetch the emails from the POP3 server at the Internet Server Provider (ISP).
All the OSX or iOS device connects to my OSX Mountain Lion server running the mailserver (i.e. Dovecot).
In my private network sending emails and fetching them using IMAP already works fine.
I am lost on this one. Any help would be appreciated.
Thanks already.
best regards,
BolkoOne solution is to use a server based software (i.e. that runs on OS X server) which polls a remote POP3 server and delivers mail to an SMTP server — the Postfix SMTP server on your OS X server (NOT Dovecot, Postfix is the SMTP server which then hands off mail to Dovecot the IMAP on your OS X server)
This software would have to be installed 'by hand' meaning you have to download the source and compile it as is standard with Linux type utilities.
Here is link to the utility 'fetchmail'.
http://fetchmail.berlios.de/index.html
You may want to confirm with the package maintainers that this would work on OS X. If you are not comfortable working at the level of installing Linux packages then I would advise not to proceed.
UPDATE: I found this page on the Apple developers website:
http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/ man1/fetchmail.1.html
it refers to the fetchmail program above so it looks like it runs OK on OS X, but you still have to manually set it up.
Another option is this software
http://www.sspi-software.com/mailfwd_macx.html
I don't have any experience with it personally and I don't know if it can run as a service (that is with no-one logged into the machine). -
I have a 2011 Mac mini, 8GB ram, default 10.7.4 server install. Filesharing, OD (replica) and most things work fine.
Recently i've set my sights on getting non-spammy logs, and as such i've started to try to resolve every repeating log message.
Today the message is:
Jun 4 16:22:42 minecraft dovecot[3586]: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Operation timed out
Jun 4 16:22:42 minecraft dovecot[3586]: lda: Fatal: Internal error occurred. Refer to server log for more information.
(every 30 seconds!)
Some poking in the config -
Dovecot SMTP (out/incoming) will not stop, if i stop it it stalls on "shutting down" and after a minute it's running again. All other parts of the server are "stopped".
As a solution i tried to configure the mail server, set it up as if i would start using it. (So it would make all configs and such) then stop the server.
Also i cleared the Mail queue and deleted all account data from the maintenance tab (server admin)
I have deleted the sockets and recreated them.
None of this worked.
Any ideas?I think i solved it, in part i already did, but i've updated this earlier post - http://meandmymac.net/1470/lion-server-still-broken-mail-this-time/
