Need to relay to ISP through port 587

Hello,
We need to set up relay through ISP smart host, but use the 587 port.
What Postfix file needs to be changed for that?
Regards
Kostas

Do I need to regenerate sasl_maps?
I can't imagine sasl_maps has any connection/bearing on relayhost
What to do with Server Admin GUI? Do I set it there, too?
For the most part all Server Admin does is view the current config file (in this case main.cf) and writes certain parameters (ones it knows about), so in this case when you open Server Admin and look at the mail settings for 'relay all messages through:' it just reads the relayhost setting from main.cf. If you change the setting in Server Admin, it just writes the value back to main.cf... in other words, Server Admin is just a GUI front end to the same file.
Therefore I'd expect whatever value you set manually in main.cf to appear when you look at the settings in Server Admin (and vice versa)

Cannot send email via Hotmail through port 587 with Secure Connection (SSL) set

Something is blocking my attempts to send email (with Outlook Express) via my hotmail.com account. The error I receive is as follows:
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'Hotmail', Server: 'smtp.live.com', Protocol: SMTP, Port: 587, Secure(SSL): Yes, Error Number: 0x800CCC0F
When Hotmail.com first changed over to a POP3 server (Sept 2009), I could send emails through them using port 587, which they require. But then something happened, with no changes on my part, to disable my ability to send.
I have checked and rechecked my Outlook Express account settings. I can send email through another third-party mail account (at 1&1 Internet.com) using port 587, which does not require setting SSL to yes. I can also ping the Hotmail SMTP server via port 587 and receive a response from it.
I connect to Verizon DSL via a Westell 327W modem/router. Clearly it is not blocking port 587 without SSL. Does it have the capability to block SSL traffic? Or is the Verizon server the culprit, not allowing emails to be sent via Hotmail.com?
Two different computers on my LAN have the same problem sending emails via Hotmail.com. I have tried everything the Hotmail people have suggested; at this point they think it is an ISP problem, hence this post. This problem doesn't make sense to me and is driving me crazy. Can anyone help me with this?
Thanks.

You can still have your reply address set to your hotmail address. And you don't have to really remember to do anything. Configure your client for the HOTMAIL account with Verizon's outgoing server. It will automatically send via Verizon. You don't reveal your verizon.net address, you are just using their server to transmit.

Need help connecting to ISP through DSL/router

Hi
I need help configuring my intel solaris8 box to get to the internet. I have dsl going into a linksys router. my windows machine have no problem using the DNS servers from pacbell. i also have DNS setup on my novell server, but the solaris8 box still can't resolve anything. I can ping everyone on my segement, I can connect to my novell web server netscape navigator but can't resolve it's name, i have to use it's ip address. I can remote logon. I lloked for a resolv.conf file but can't find one, help!!!!
Danny

Edit /etc/resolv.conf (it may not exist) with the following lines:
domain your.domain.name
nameserver your.primary.dns.ip
nameserver your.secondary.dns.ip
search your.domain.suffix
The last line is optional, but please do substitute those values for the ones that you use.
As far as a default route goes, just edit /etc/defaultrouter (may not exist) and put the ip of your default gw on a single line.

Mail, returned mail, blacklisted ISPS and port selection

I live in Spain and my e-mail, especially to US friends and colleagues, is increasingly being returned to me, even though I have been e-mailing them for years, because it is now being identified as spam. E-mail to family, friends and colleagues in Spain and other countries is rarely treated this way, I suspect because US ISPs are more pro-active in blacklisting spammers.
Error 526, listed on the returned e-mails, is identified by AT&T as being a spam problem. The site at spamhaus.org identifies a whole IP range, within which the IP assigned to me (I'm not sure whether it is assigned to my computer or router or my ISP's outgoing mail server(s)) as a spam source, even though I send no spam at all.
I use Mail 2.1.3 as part of OS 10.4.11.
I have spoken to my ISP at huge length, and expense, about this and they say they can do nothing to get their IP range removed from the blacklist, although various websites make it clear that ISPs can do this, if they want to. The real problem is that there is very little choice of ISPs in Spain, and the ISPs are all as badly run as each other and not one of them is remotely service-oriented. So changing my ISP will not achieve anything. The secondary problem is that I appear to know more about ports, and mail programs than the 'technical' staff I am talking to at my ISP, so they just say they do not know how to or cannot help me.
Two possible solutions occur to me.
1) I could ask for a fixed IP address, paying a little more each month. Would such an address apply to my computer, my router or all 4 or 5 computers, wired or wireless, on my LAN? Would a fixed IP address normally fall outside the range of dynamic IP (address) numbers).
2) The standard smtp port used by Mail for outgoing e-mail is port 25. Authentication, by my ISP, is by username and password. However, I have read that port 25 is filtered by receiving ISPs for spam, in other words port 25 does not do a 'full' authentication job. In contrast, port 587 is supposed to do a 'full' authentication job, and e-mail proceeding from that to other ISPs is supposedly not filtered. So I have tried sending mail out through port 587, but this doesn't work. Do I have to turn SSL on? Do I need to open port 587 in my router's firewall? And does my ISP have to make some adjustment at their end? They say they cannot and do not have to, and that I can send e-mail through any port I choose to???????
I have looked to see where port 25 is currently open, but there is no mention of Mail or port 25 in any of my router settings, so other than specifying in Mail preferences that the smtp server port number is 25, or 587, I don't know where else to look.
All help would be deeply appreciated.

1. That likely won't make a difference at all, any IP the ISP gives you will be in the banned range.
2. None of that matters at all to the "ban", different port usage is strivkly dependant on your ISP's set up on their end.
I think your only solution is getting something like a free gMail account. After you sign up...

RVS 4000 on Port 587

hi
I just bought RVS 4000 a week ago. My previous router can send email through port 587,
Ever since i bought RVS 4000, it stop sending emails. I opened port 25 and I have tried all my best to do port forwarding to port 587 but still it cannot send email.
My ISP is using port 587.
Please help help me on this. What should i do to be able to send email on port 587?

Hi Lui,
When you say send mail on port 587, are you referring to sending mail from the LAN to the WAN on port 587? Or a port forward translation from 25 on the WAN to 587 on the LAN?
On the RVS4000, you can perform port translation by going to the Firewall Page, then Single Port Forwarding. Create an application name (text based, will not affect config) and then you can choose an external port to internal port. Lastly point to the internal IP address of the mail server.
If you are referring to sending mail on port 587, the router is by default going to allow all outbound traffic out and will not block or filter ports.
Please let me know if this resolves your issue.
Thanks!
Dave

I need to modify Postfix to listen to port 587

Mountain Lion Server OS X 10.8.4
Running Mail service with Postfix and Dovecot. In production with several mailboxes.
I need to modify Postfix to listen to port 587. I should be able to telnet to port 587, and finally send mail via 587.
587 already redirects to 25 via the firewall, but external devices need to visit the internal subnet without modifications to the mail app.
At this stage I just want to get it working with password authentication. SSL is a project for another day.
Here's my understanding of the OS X Postfix config:
/etc/services file:
Maps service names to port numbers. Port 25 is "smtp" and port 587 is "submission".
/etc/postfix/master.cf file:
Loads Postfix preferences. Service configurations for "smtp" and "submission" are listed at the top of the file. Each service configuration can be modified with parameters (-o variable_name_here=value_here).
I found many discussion boards with instructions for enabling 587. They suggest removing the comment syntax for the existing "submission" line:
# submission inet n - - n - smtpd
My server didn't have a comment, the line was already enabled:
submission inet n - - n - smtpd
I restarted services and 587 didn't work.
Then I tried a more direct approach:
587 inet n - - n - smtpd
This had no effect.
After each attempt to enable 587 I test with:
telnet 127.0.0.1 587
And I get: Connection Refused
I used the Server app and turned Mail off and on. This stops and starts Postfix.
I also used commands to restart Postfix:
postfix stop
postfix start
sudo postfix stop
sudo postfix start
postfix reload
sudo postfix reload
Nothing opens 587. Any ideas? Thanks in advance for your insights.

@Kraftwerk: You cannot change the TCP port used for SMTP. Well, technically, you can, but then no other mail servers on the Internet will find and communicate with your mail server. So... forget that.
The ISP controls the terms and conditions for the network connection, and particularly controls the network and network access. There's just no way 'round that either, as the ISP has the network position to implement port blocks and firewalls, and usually the contractual authority to allow or deny access.
With the proper (static) network connection and proper DNS, there is nothing to struggle with; this stuff works.
Which implies your ISP does not offer static connections, or there's an ISP error, or you're attempting to operate a mail server on a dynamic address. None of this works.
You might try mailhop service — if that's permitted within the limits of the terms of service — but it'll be easier and cheaper to host your mail elsewhere. Or to get a static IP address and proper public DNS, if your ISP offers that.
SMTP services are also tied to DNS, as well; other mail servers use DNS checks to detect rogue (spam) servers, and a mail server erroneously configured on a dynamic IP address will have mismatched DNS, and other mail servers will detect that and drop mail from and often to that mail server; that server is indistinguishable from a spam engine.
There's rather more the ISP can do as part of best-practices networking, too. TCP port 25 connections both inbound and outbound are usually spam engines operating on malware-infested, so it's common to block that traffic to reduce the volume of spam. Various ISPs will further blacklist dynamic IP address blocks, which means other SMTP servers using these blacklist services will ignore servers in these address ranges.
Get static IP. Or host elsewhere. Or (if permitted) mail hop.

Sending email using IMAP through SMTP Port 587

Hi,
I have been sending Mail Merged email to people in organizations that I am active in, using IMAP embedded in StarOffice 5.2 (on Windows 98 Second Edition). This worked fine until a few weeks ago when I received an error message stating that AOL, as part of their anti-spam efforts, was no longer accepting third-party emails on default port 25. All third-party email must now use port 587. I looked in the IMAP dialog and in the Tools -> Options dialog, but did not see any place to change the SMTP port. The AOL error message information page had instructions for changing the port in other applications (Outlook, Eudora, etc.), but not for StarOffice. So, I have some questions:
1.Is it possible to change the port in StarOffice 5.2?
2.If not, how does StarOffice 8 send Mail Merged email? Does it use IMAP, and if so, can the port be changed?
3.Also, I like the integrated configuration in StarOffice 5.2, where database fields can be directly accessed in the Insert -> Fields -> Other dialog. In looking at the Mail Merge section in "SO8_What's New.pdf", it appears that Mail Merge in StarOffice 8 is restricted to predefined fields. Could I still access fields from my existing databases?
These is a lot of questions, but right now I am blocked from sending Mail Merged emails which is imparing communications with volunteers who are running educational programs. I appreciate any and all help that anyone can provide.

Please try this out!!!!!!!!!
You can send emails using Outlook also. You can send email over Microsoft Exchange with this object (or another email server, using IMAP/POP).
Sub SendMailOutlook(aTo, Subject, TextBody, aFrom)
'Create an Outlook object
Dim Outlook 'As New Outlook.Application
Set Outlook = CreateObject("Outlook.Application")
'Create e new message
Dim Message 'As Outlook.MailItem
Set Message = Outlook.CreateItem(olMailItem)
With Message
'You can display the message To debug And see state
'.Display
.Subject = Subject
.Body = TextBody
'Set destination email address
.Recipients.Add (aTo)
'Set sender address If specified.
Const olOriginator = 0
If Len(aFrom) > 0 Then .Recipients.Add(aFrom).Type = olOriginator
'Send the message
.Send
End With
End Sub

SMTP does not start on port 587

I just activated IMAP and SMTP on an old G5 Server running the latest version of Leopard.
Everything, but for one thing, runs fine. IMAP works correctly from both the local network and any distant network I could try it. SMTP runs fine on the local network but only on port 25. Nothing is listening on port 587, or 465. Hence, SMTP does not work from a distant network.
The firewall is off, but even from the localhost, or any machine for that matter, telneting to port 587 does not get an answer :
telnet 127.0.0.1 587
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host
I did activate ssl for smtp in the Advance>Security tab. It uses the same selfsigned certificate as IMAP, which works fine. I can also tunnel in from a distant machine and SMTP will work.
I tried to uncomment the following four lines in master.cf
#smtps inet n - n - - smtpd
# -o smtpd_tls_wrappermode=yes
# -o smtpd_sasl_auth_enable=yes
# -o smtpd_client_restrictions=permit_sasl_authenticated,reject
but I only lost connection on port 25 and got nothing on port 587. This feels good, but I have no idea where to go from here.
Any one has any suggestion ?

I understand well that this is exactly SMTP, but just running on a different port, port 587, for submission, while port 25 is for relaying between server
That's pretty much it, except that port 587 should be configured to accept mail from authenticated users only (as determined by the line:
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
This enables authenticated users (e.g. users who have accounts on the server) to send mail through the server without restriction (e.g. they can be remote) while unauthenticated users (including remote mail servers sending mail to your domain) use the standard port 25
should I uncomment the lines for smtps in order to use SSL ?
smtps is still different from SMTP (25) and submission (587). Both SMTP and Submission can use SSL if you enable tls support - tls enables a connection to start off insecure/unencrypted and switch to encrypted if both the client and server acknowledge they support it. It's generally not recommended to require SSL/TLS unless you're sure every client that's going to use that service can support (and is configured to use) encryption.
smtps (which requires SSL) is now deprecated in favor of TLS (which allows the server to support both encrypted and unencrypted connections on the same port number).

Port 25 works fine for SSL/SMTP, but not port 587?

So after doing a rather painful migration to new hardware to support 10.5 from a previously working 10.4 config...
I got SSL working -- web service is fine, mail service is fine for all ports for POP and IMAP...but not port 587.
- It's open on my firewall
- There's no software firewall impeding it
- Trying to telnet to port 587 results in nothing
It's as if the server isn't even listening to the port...
And the odd part?
- Mac OS X desktop clients report they can't connect on 587. Changing the port to 25 and leaving everything else the same (auth type, username, password) -- suddenly it works...BUT
- The iPhone is configured for port 587 and works every time.
My guess it that iPhone auto falls back to port 25 if all else fails, I can't explain why it would work. Bigger question, I suspect something got munged in the migration...is it possible it needs to be told to listen on 587 as well?

I saw that site...it mentions adding port 587 specifically -- or commenting out "the appropriate lines of master.cf"
I assume that means to uncomment out the submission port in that file -- or would it be better to add 587 specifically?
Also, I never allow unauth SMTP (even inside my network) -- I would want to continue to impose that on the submission port and the normal port 25; how do I do this?
Thanks in advance for the help.

Relay Outgoing Mail Through Host Not Updating

We relay our mail through an external company and I have added the entry to Relay Outgoing Mail Through Host field and enabled the tick box. What ever I do I cannot get these changes to take affect. I have tried modifying the main.cf and enabled the relay option without any joy. After modifying these I performed a full restart but it still hasn't taken affect.
This has been working up to now but after a power cut stopped for some reason.
We are running Mac OS X Server 10.4.8.
Thanks
Ross

I'd noticed a small glitch with the GUI during earlier testing. Might not clear things for you but worth trying...
Set it with the Relay Outgoing Mail ticked and relay server entered - click Save.
Wait for whirling update thingy to stop.
Delete the relay server name then tab out of field (field fills with greyed out "relay.example.com"), only then untick the option - Save.
Wait for whirling update thingy to stop.
Tick the option, fill in the relay server - Save.
If no change, people will probably need the unedited output from "postconf -n" and an example mail.log entry showing an outgoing message leaving the server.

Comcast Port 587 Not Working

Comcast contacted me to change to port 587 because my account was sending spam. I've done this and can't send or receive email. I've restarted mail, my computer, I've checked and unchecked SSL. I've contacted Comcast and they say it's a Mac issue. I'm clearly doing something wrong, I just can't figure out what it is. I get mail on my iPhone using 587, but not my iMac. If it were possible to cut and paste on the iPhone, I wouldn't care, but need the iMac for document creation and response.
Anyone know what little thing I'm not doing that could fix this problem?

I recieved a similar email from Comcast saying "Comcast has determined that your computer(s) have been used to send unsolicited email ("spam"), which is generally an indicator of a virus."
I have no idea why I recieved this (waiting for a representative from Comcast Customer Security Assurance to call me back), but I'm sure it's related to the port change from 25 to 587.
Now I've been using port 465 for secure SMTP connections for... years probably. However, the configuration for server authentication seems to have changed.
The solution was to change the username under authentication from "userxyz" to "[email protected]". (I use my primary Comcast username, in case that makes a difference.)
The best part was when I called Comcast and they told me I had to call Apple for help configuring the Mail.app client. Yeah, it's their problem.

Elements that need to be paid only through Cheque

Hi all,
I'm on R12 International HRMS.
I have a few Elements that need to be paid only through Cheque.
These elements are run separately as a quick pay or by selecting an element set and assignment set and run the payroll process separately.
What is the best approach to go about this requirement.
The default payment type defined is Cash Type.
How can I make sure the payment for these element is always Cheque
And also how do I customize the Cheque Writer(Generic) Process to include my design of the cheque.
Thanks

If you are using Assignment set , run the payroll using assignment set and after that run cheque writer and make sure u did not add
any bank details to him , it will pay by cheque as per my understanding

Leopoard / Mail 3.1 and port 587

Hello,
I am starting with leopard and mail 3.1.
I have to change the port to go to port 587.
I canot find where to do it.
Help please.

Hello and thank you.
However, I knew how to do it in previous release of Mail.
As you said : there was a place called "réglages des serveurs" (tune the s"erveurs")
Mail, preferences,account, advanced ...... but the "reglages des serveurs " does not exist anymore
in Mail in the new release Mail 3.1
Therefore I dont know how to change (SMTP) PORT from 25 to 587.

There are 2 options for things like this:
1) Use Runtime.exec() to execute some command or application and parse the input from it.
2) Write some native code and use JNI to call it.
