Let's say I have a postfix box, named mail.thespider.com, which is setup to handle virtual mailbox domains. One of these domains will handle is, thespider.com, and my email address in that domain is boris@thespider.com. As I setup dovecot, I can telnet to the pop3 port (110) and test it by logging in as boris@thespider.com (I would try the imap port but I do not know how to login to imap from the telnet prompt):
[raub@taz ~]$ telnet mail.thespider.com 110 Trying 192.168.1.12... Connected to mail.thespider.com (192.168.1.12). Escape character is '^]'. +OK dovecot ready. user boris@thespider.com +OK pass creepycrawly +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [raub@taz ~]$
How would I do the same under thunderbird from a machine in the same lan (taz.thespider.com)? It seems to keep trying to login as boris@mail.thespider.com, which will not fly.
