Email problems after upgrade

[bjarne-j]

hello,

I have just upgraded ispconfig 2.2.25 from 2.2.23. Everything works fine except email. It's possible to login to webmail(roundcubemail), but from an email-client the connection is trying to load until time-out.

Hope someone can help with this issue

Bjarne.

The issue is isolated to IMAP accounts. POP3 works just fine.

[till]

ISPConfig does not configure imap or pop3 directly, so this issue is most likely not caused to the ISPConfig update.

Which errors do you get in the mail log file?

I found more errors in my setup. So I reinstalled. It works now. I just have to fix my certificates for postfix and courier.

I found this for courier:

Edit /etc/courier/imapd.cnf
rm /usr/lib/courier/imapd.pem
run /usr/lib/couier/mkimapdcert

I restarted courier-imap, courier-imap-ssl, courier-authdaemon after making the new cert.

I want to change the CN to mail.domain.tld in order to awoid the warning from Thunderbird. When I run mkimapdcert it generates the new cert. But when thunderbird downloads the cert the CN is still localhost(as by default).

The issue is mentioned in this thread also: http://www.howtoforge.com/forums/showthread.php?t=1168

Solved.

I had to edit /etc/courier/imapd-ssl. TLS_CERTFILE has to be changed to /usr/lib/courier/imapd.pem instead of /etc/courier/imapd.pem

Thanks anyway.
