If it is, how can Postfix and an imap-server run on the same host.

By definition, an imap server listens on the imap port (143, 220 or 993, depending on dialect). port 25 is the smtp port, so that requires an smtp server, such as postfix. Some program might conceivably be both imap and smtp at the same time (though the only example I can think of is exchange), but it's still two different functions. mail is delivered by telling your mail delivery system to deliver it to the imap server. In the case of postfix and cyrus, you set up a named pipe for the communication between smtp and imap. In the case of UW-imap, I seem to remember that the imap server worked on the standard mbox spool files that most mail delivery agents use by default.

Email is not delivered to an IMAP server, they are delivered to a local mailbox. IMAP server is just a program to access these mailboxes.

Port 143 usually. 25 is smtp.

If it is, how can Postfix and an imap-server run on the same host.

Two different programs, different ports, different functions = no conflicts. ;-) -- Joe Morris New Tribes Mission Email Address: Joe_Morris@ntm.org Web Address: http://www.mydestiny.net/~joe_morris Registered Linux user 231871 God said, I AM that I AM. I say, by the grace of God, I am what I am.
