With some help from darix I finally managed to get postfix with virtual aliases from text files + dovecot (instead of courier-imap) with virtual users working! \o/

I always thought I was using the IDLE extension for IMAP in Thunderbird but that does not seem to be the case, because courier-imap did not support it (maybe I just misconfigured it, who knows). With dovecot I get notifications about new mails immediately... When I send a mail to myself the mail appears even before Thunderbird is able to close the ‘Sending mail’ window! And dovecot seems to much faster when copying/deleting/moving emails as well. :)

Tomorrow I’ll do the web part which is going to be more fun I think, but today I certainly learned a lot about postfix. I was backed up by some howtos though, namely http://www.howtoforge.com/linux_postfix_virtual_hosting and the dovecot wiki

And btw I also installed DSPAM (which replaces the previous memory hog amavis + clamav + spamassassin…) using http://gentoo-wiki.com/HOWTO_Spam_Filtering_with_DSPAM_and_Postfix—I don’t know if it is working yet as darix gave me some postfix rules which already prevent a lot of spam senders from successfully connecting:

smtpd_sender_restrictions = reject_unknown_sender_domain
smtpd_client_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unknown_client
smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname
