Hi, I've built mail servers for years and I've now built a Fedora core 4 server and needed an imap/pop server. Since courier-imap isn't on yum i just installed dovecot instead. Worked fine with pop3 but imap with squirrelmail kept giving me login errors and logs showed almost nothing. I finally got fed up with dovecot and switched to source of courier-imap and installed authlib as well. funny enough I'm getting the same problem. I tested it with Mutt and it works fine when using TLS, but turning TLS on squirrelmail just gave me : Error connecting to IMAP server: tls://localhost. 0 : and yet with Mutt it works fine.. mutt -f imap://[email protected]/INBOX so i'm lost why squirrelmail and Ueibimail can't login with imap.??? heeelp.. spend all day on this already.
