Is my mail server being used to relay spam?

I've just setup a new OS X server (10.5.6). The only two services I have running are mail and web. The web services seem to be running well. However, mail is giving me problems. Specifically:
I have "Relay" set with two ip addresses. The first is localhost: 127.0.0.0/8 and the other is: 216.23.173.96/28 which is the ip network my server is on.
However, when I look at my SMTP log - set to "debug" level - it shows lots of mail activity including this entry:
"Apr 23 19:53:34 MMcolo postfix/smtp[39718]: DBEAE98602: host g.mx.mail.yahoo.com[206.190.53.191] refused to talk to me: 421 Message from (216.23.173.107) temporarily deferred - 4.16.50. Please refer to http://help.yahoo.com/help/us/mail/defer/defer-06.html"
That url takes you to a page that states that my mail server may be being used as a spam server, so I can't send mail to yahoo accounts.
The logs also show multiple attempts to connect to a variety of different domains. Since I'm the only one with an account on my server and I know I'm not sending those emails, it makes me concerned. Anyone have any suggestions or advice?
Thanks in advance,
John

I just went through this when I migrated to a new ISP. However, it was Comcast that was blocking me with a similar message. We thought our ISP had provided clean IPs. So I called Comcast and they were actually very helpful. Found out that in addition to some blacklist providers (spamhaus, etc) they are also using senderscore.org and trustedsource.org.
Turns out the block was due to the IP being listed as malicious on trustedsource.org. Got a new block from my ISP and all is now good. (trustedsource shows as unverified for the new, but that's ok with Comcast). From what I see unverified is the standard state for very low volume sites. There are some other sites for this "credit" score as well. senderbase.com is another (based on Cisco's IronPort).
So I would follow the link yahoo gives and select the part that says to send yahoo the messages and let them help diagnose the problem. If they're willing to help, use that.

Which mail server is used in a webapp?

Hi all,
I have a Webapp where the users can send an email
to me including the parameters of a form
( <form action="mailto:[email protected])....>
<input type="hidden" name="param1" value="xx"/>
Now depending on which mail client the user has on his machine the resulting email differs, sometimes the parameters as 1 attachment, sometimes xx attachments.
So I want to implement it with javamail-api.
MY question: I have to tell the API the name of the mailserver. How can I know what mail-server the user uses? Or are all these emails processed through my own mail-server?
Please help me to understand it. Thanks a lot in advance,
Peter

Hey ho.
You have to hardconde the mail servers in your code to point to the mail server you use (= your ISP's server) or host (= Your own mailserver). All the mails are then processed through that specified server.

Is Flash Media server being used commercially--TV? etc.

Would much appreciate some concrete (live time) examples of Flash Media server being used in a commercial enterprise. Prefer domestic (US) but any will be great. Any closed network systems such as a multi-campus university?
Is it being used only as a one-to-many distriution tool? Or, is it being used as a many-to-many remote classroom environment?
Thanks,
Greg. Eckrich, aka
chicagohotdog

On your requirement of having your web app manage access, your developers will need to program some supporting classes on the FMS side. If the web app is to maintain access control, the flow will work like this:
1. User credentials will be provided to the client side application (the .swf) either by manual entry via a form, or by runtime variables provided in the flash object embed code.
2. When the client connects to the FMS application, the credentials will be passed in the connection request
3. The FMS application will make an HTTP request of the web application server to validate the credentials.
4. The web app server will reply with a pass/fail result
5. The FMS application will accept/reject the connection accordingly.
Server side programming for FMIS (server side actionscript) is Javascript, so if your developers are already experienced with Javascript, they should have no problem getting comfortable with the FMS API.

Mail server cannot use certificate because.. the filename is too long ?

Hi,
For some reasons, yesterday, I created a new certificate on our server (XServe with Mac OSX Server 10.6.2) and I assigned this certificate to the mail server. Since then, we are not able to connect to our mail server. We receive an error saying the server cannot open a connection on port 993.
I looked at the mail access log and I think I might have found the cause:
Jan 7 09:20:25 xs1 dovecot[1944]: Fatal: sslcafile: Can't use /etc/certificates/LemieuxBedard.com.264472D0EC029B3194A4B779D2187278189E8352.ch ain.pem Bedard.48DFB4D5FA4786D77DEF02C72591002CC865D5E1.chain.pem Bedard.48DFB4D5FA4786D77DEF02C72591002CC865D5E1.chain.pem Bedard.48DFB4D5FA4786D77DEF02C72591002CC865D5E1.chain.pem Bedard.48DFB4D5FA4786D77DEF02C72591002CC865D5E1.chain.pem Bedard.48DFB4D5FA4786D77DEF02C72591002CC865D5E1.chain.pem Bedard.48DFB4D5FA4786D77DEF02C72591002CC865D5E1.chain.pem: File name too long
I don't understand why the name is too long since the previous certificate had a name even longer. Is this a bug that should be corrected on the next update or have-I indeed done something wrong? Right now, I disable the certificate on the mail server and it works. However, I'd really like to use the certificate.
Thanks for any help.

No, you didn't do anything wrong, JeanPhilippe. I'm right there with you. There's even another thread on this issue:
<http://discussions.apple.com/thread.jspa?messageID=10808126>
I had the same problem: IMAP & POP services would not launch using SSL. Finally got it resolved today. It had nothing to do with certificates and their names, or creating them in openssl, and everything to do with a botched dovecot.conf file, courtesy of Server Admin.
It appears that every time I changed the certificate for IMAP & POP SSL in Server Admin, it appended the new selection to the dovecot.conf file on 3 separate lines. The result was an unhealthy list of every certificate file Server Admin had ever been pointed to for this service.
After making a backup, I edited the file (/etc/dovecot/dovecot.conf) down to the single cert file I wanted it to use. It happened to be first in the list, FWIW.
If you want to duplicate this, look for the lines beginning with:
"sslcertfile"
"sslkeyfile"
"sslcafile"
Obviously you need to be careful in there. But I did not even have to bounce the service before it took my changes. Thankfully, Server Admin did not overwrite my edits (which I've seen happen with manual config of other services, such as the iChat service.)
Good luck, and let me know if I can provide more detail.

Best e-mail server to use with iPhone and Mac?

I've always used hotmail as my e-mail server. Recently, I've started using the Mail app on my MacBook Pro instead. I really hate that the mail on my iPhone and the mail on my Mac do not sync with one another. Any suggestions??

should I forward any emails I would like to keep to my gmail account or is there a faster way of doing this?

Cannot send mail - server does not allow relaying

I keep getting a sporadic error message on my ipad: "cannot send mail. The recipient was rejected by the server because it does not allow relaying". Sometimes it doesn't happen and the mail sends fine. Sometimes I get the error message but the message then sends later. Sometimes it never sends.
Can anyone help?

Hi, I've suddenly encountered this problem. I have a 1st gen iPad. I've reset, deleted, re-added, turned on both outgoing servers, added my password--this last doesn't stay in the primary outgoing server field; when I go back in, the password field is filled with the (optional) text again and when I 'click' into the authentication box, the password is no longer checked. However, these are all filled in the secondary outgoing server, so it shouldn't matter. Restarted the iPad a couple times. Using system 5.1.1--I think that's as far as I can go. Any miracles out there?

URGENT! PLS HELP... using JAMES as mail server

hi, first of all... happy new year to everyone...
i am currently developing a web based application and one of the component in the system is using JAMES as mail server. I am done some modification in config.xml in JAMES, now the problem is i can only send internal mails instead of external one, such as hotmail and yahoo.
The error occurs as below:-
RemoteDelivery: Exception delivering message (Mail1041375079561-0-!448616653-to-hotmail.com) - Could not connect to SMTP host: hotmail.com, port: 25
How can i send mails to hotmail and yahoo users or any other external mail?
Can anyone pls help me to solve this problem?
Thanks in advance.

sounds like a network problem rather than a JAMES problem. Have you confirmed that you can ping the hotmail mail server, and then that you can "telnet" in to it on port 25?
If you have a windows machine handy, you can find out the IP address of hotmail's primary mail server by using nslookup:
C:\>nslookup
set type=MX
hotmail.comIf you don't get anything from this, it would indicate a DNS problem. Once you have the IP address, try to telnet to it on port 25:
C:\>telnet 65.54.254.129 25
Here's what I got...
220 mc1-f3.law16.hotmail.com Microsoft ESMTP MAIL Service, Version: 5.0.2195.5600 ready at Wed, 1 Jan 2003 21:19:03 -0800
If you aren't able to connect, it's probably either a firewall at your end blocking outbound TCP traffic on port 25 (or possibly all ports), or a DNS issue, or some sort of routing issue with your ISP

Go to content area.
Portal Content à Content Provided By SAP à Collaboration and right click.
Select New from PAR à System.
Choose the iview com.sap.netweaver.coll.app.gw and hit next button. Select Java_Mail option and hit next button. Enter appropriate System Name and ID and hit next button. Hit finsh button and open object for editing.
Select System Aliases from display option and add an alias for the system. Save changes.
3. Create Mail Transport by going to
System Administration à System Configuration à Knowledge Management à Collaboration.
   Click Groupware Transports in content area.
   Select Mail Transport on next screen.
   Click New button and create new mail transport definition.
   Give SMTP server being used in organisation, Inbox for Sent messages folder, and give
   system alias created in step 2 as alias.
4. Mail channel server too has been set up.
Thanks and regards,

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

ICloud mail server - Unable To Send With Apple Mail client

OS X 10.10.2
Mail v 8.2
iCloud mail
I am still able to receive messages but suddenly unable to send. Messages stay stuck in Outbox.
Mail Connection Doctor reports no problems:
If I setup MS Outlook for Mac 2011 with this iCloud account, I am able to send and receive like a champ.
Once it starts working, is there a way to change the outgoing mail server to use SSL, i.e., turn SSL to "ON" ?

Yes, I did. It doesn't show up in the logs because, I'm unable to send a message - it goes to the outbox immediately. And this led me to the conclusion below.
And by the way, I did get in touch with Apple Support who went through a number of troubleshooting scripts (including trying to use GMail's mail servers) and ultimately had me reinstall OS X from scratch. None of this worked.
Now this problem of being unable to send mail via my iCloud account, from the Apple Mail client, started only around the end of Feb. What I finally figured was that iCloud mail was using random ports on my machine to invoke its SMTP port. Everytime I would disable the firewall on my router completely, iCloud mail was able to send just fine. Recall that incoming was (and still is) working fine. Anyway, I installed wireshark to ID the ports that were being used when the firewall was down. I set up triggers on my router to open these up, turned on the firewall, but it just isn't working. I will have to play around with wireshark and see if I can figure out what ports need to be opened. Unless you or someone else knows. If I figure it out, I will post it here. Mind you, that I need to figure out not only the source ports that need to access port 587 but also what the real target port is (because I don't think it is just 587 as Apple claims).
By the by, when I asked the Apple Technician (some guy who I was transferred to after 3 other people - the one who asked me to reinstall Yosemite) if there was a way to change the outgoing mail server to use SSL, i.e., turn SSL to "ON", he said no there wasn't and why would one need to secure the traffic to Apple's SMTP server anyway? Seriously?

TS3899 The email arrives with no problem, but when making a rely, the message pops up stating "The server does not allow relaying" and the reply is not sent.

Received an iPad for Father's Day; during email setup, not able to send a reply to an email as a message appears stateing "Message not sent as server does not allow relaying." Can receive emails with no problem. Whoes server, theirs or mine.
