[Dovecot] Don't Know Where Emails Are Or What's Happening
Hi;
I'm new to Dovecot and Postfix. I'm trying to enable these with MySQL support and postfixadmin. I've got all those services up and running (finally!); however, I can't figure out if the emails are being received and/or stored. I'm pretty sure Postfix is receiving them because I dealt with certain errors and they're now gone. Here's some data:

I reckon the failing of mysql inquiries just has to do with hackers trying to hack me. The TLS problem isn't mission-critical since it's just getting disabled.

Yes, TLS is isn't an issue - although you have it incorrectly configured. That would be the last thing you need to implement/fix. For now disable it in postfix and dovecot.

At a minimum your daemons are running - congratulations! That's always a good start and I remember when I was setting up the sense of achievement that brought. But for now you need to get postfix working (their list is great). Perhaps if you give more details on your system I can point you to a better howto. And maybe more information on what you're trying to achieve? Virtual domain? Virtual domains? Multiple users? Local users? All these have an impact on what the solution is.

First, I'm subscribing to postfix as per your recc and I upgraded my dovecot. What the heck was I doing with such an old version?! lol. My OS is CentOS.

I have clients with their various domains hosted on my server to whom I need to serve email. There will only be me on a slice of one machine interfacing with dovecot/postfix. I have integrated/am integrating Amavis, ClamAV, Spamassassin, PostfixAdmin and SquirrelMail. Thanks, Jack

Well, unless the link I sent you helped you with the the table locking problem, ask over there for help on making sure that postfix is accepting and delivering mail. Or accepting at least.
Did you plan on having postfix or dovecot do the delivery (using dovecot-lda)?

Okay - fairly common setup. I don't use postfix-admin, but if that's what created your mysql tables that could also be a starting point to look for the table lock errors.
Good luck!

postfix as MTA, dovecot as MDA. Am I missing something here?

Are you using Maildir or mdbox format for the users? Postfix can write the mails into the Maildir, but so can Dovecot. So, if you're using maildir you can either have postfix put the mail there or you can hand it off to Dovecot and have Dovecot put it there..
But let's fix postfix first before you worry about that.
Simon
Wait a minute! PostfixAdmin has no problems with MySQL. They have a setup page that verifies the MySQL connection among other things, and everything checks out perfectly well.
At any rate, Simon, am now communicating with the Postfix list as well ;) Thanks, Jack
