Around 48hrs ago I noticed that yum downloaded and installed an absolute slew of updates (around 248 I think). Since then I am unable to download any of my e-mails via outlook externally, although I am positive they are actually being delivered as I can read them with the ‘Read User E-Mail’ function in virtualmin.
I have a default Centos 5 install with virtualmin… nothing else fancy or unusual. Any ideas whats gone wrong?
outgoing mailserver no longer accepted connections at smtp.domain.net so I changed the clients outgoing mailserver to mail.domain.net
UIDL format had changed from Courier2 to Not Set
I’m guessing the config file was overwritten during the upgrade to 5.1?
Thankfully I have a limited number of clients on this box, so it was not a huge headache.
I changed the UIDL back to C2, restarted Dovecot and Postfix.
I did not need to make the login_process_size change listed above, which seems unnecessary unless you have massive numbers of of mail users with frequent send/receive sessions… I’m guessing dovecot & postfix just needed a restart in this case?
I actually found the login_process_size=32 line commented out after comparing the Dovecot config file to one on a server that has not been updated. Simply uncommenting this line fixed the problem.
