I've used the Ubuntu 8.04, postfix/courier with virtual users HOWTO which works great. I'm in the process of moving postfix to it's own slice, however it will still connect to the original mysql server (i.e. a different slice). I've changed all the mysql host settings. I can send emails via telnet and receiving email works great but for some reason I can't send from my mail client. It seems to take a long time sending then finally comes back asking for your password again. This makes me think it's trying to connect to mysql and timing out but I can connect to the mysql server no probs from the command line of the new postfix slice. I also can't see any related mysql errors in the mail.log/auth.log. Anybody have any ideas what it might be or how to fix this?

Figured it out - it was mysql as I suspected. Incase this helps someone else: I couldn't see an error until I grep'd the log files and found some errors tucked away in auth.log Code: grep 'mysql' /var/log/*.log Gave this: auth.log:Aug 24 12:01:59 mail saslauthd[xxxx]: pam_mysql - MySQL error (Can't connect to MySQL server on 'x.x.x.x' (110)) This led me to look at the /etc/pam.d/smtp file and I realised I'd put a mistyped my other servers IP address - doh. Oh well you live and learn!
