Postfix Issue

[thetekgeek]

Hello all, I finally had to register rather than reading the threads because I came across an issue that I cannot figure out.

Here is what I have...

Fedora Core 5, running ispconfig with postfix and spamassassin (spamassassin is not very well configured due to lack of time so it really isnt doing anything as of yet). This has been running for several weeks without a single hitch. Until this morning. It seems as though incoming email is getting lost somewhere, but I cannot find where it is going. I have another mail server and I can read in the logs where mail is being delivered to the postfix server, but when users check their mail, there is nothing there. There is no problems with logging into their mail accounts, everything seems fine. Just no mail.

Anyone encounter a similar issue? And have some information on where I should take it from here?

Did you enable Maildir in ISPConfig (Management -> Server -> Settings -> Email)?

[thetekgeek]

Yes, I did. I believe that is one of the steps in your FC5 perfect setup.. Which is the tutorial I used for the initial setup. (Thank you very much for your work in helping!)

What's in your mail log?

[thetekgeek]

Yes, I just checked it.. The mail log is pretty long.. Is there anything in particular I should look for? I do notice a line saying "Cannot Load Certificate Authority Data" could this be a certificate issue?

There is also this line..... comes up every so often in the log.
warning: TLS library problem: 3143:error:2006D080:BIO routines:BIO_new_file:no such file:bss_file.c:125:

Send a mail to your server, and then post the mail log excerpt from that time.

Ok, here it is.. I sent a test mail at 8:32 AM.. Here is the log for that time

I don't see any mails arriving in that log. Are you sure that the MX record for your domain is pointing to the correct server?

[thetekgeek]

It is possible that is the problem, I am not doing the DNS forwarding for this domain. It is done at the isp's DNS server. However, I would think that the mail would come back as undeliverable. But, it doesn't.

The website that is running on this domain is still working just fine. So, I am inclined to think that it is not a forwarding issue. But, it certainly could be. Just to be sure I will call the isp and see if they are forwarding port 25 to the proper public address.

Can you post the domain name here that you're sending to?
