Problems with mail server setup. (qmail based)

[diskreet]

Okay I followed this how-to ( https://forums.gentoo.org/viewtopic.php?t=171499 ) exactly, but I'm having some issues. I eventually got the postmaster login working and set up some email accounts, but I'm unable to log into them via pop3 or webmail, or even IMAP for that matter. Anyone else have similar problems?
