I have installed the whole system exactly as detailed in the Mandriva 2006 Perfect Install and the installation instructions of ISPConfig. I haven't modified anything as you guys know a lot more about it than me. What is the default? I did a "locate" for courier and dovecot and got no result (apart from courier font). If I "locate" pop I see /usr/sbin/ipop3 and ipop3s and ipop2.
/usr/sbin/ipop3d results in:
+OK POP3 webserver.mydomain.com 2004.89mdk server ready
/usr/sbin/imapd results in:
* OK [CAPABILITY IMAP4REV1 LITERAL+ SASL-IR LOGIN-REFERRALS AUTH=LOGIN] webserver.mydomain.com IMAP4rev1 2004.357mdk at ...
The thing is that everthing was working fine and then just stopped.
The only change I can remember making in the last week or so was adding a co-domain to one of my domains. That was mail.mydomain.com so that I could put that in my MX record in the DNS (Zoneedit, not local. I am not serving DNS to the Internet from this server.) The domain that I changed is not the main one that I use for email.
