hi, I'm look around to find a usable imap server and find dovecot. I read all the docs, but I've got a few questions:
- currently we use courier (since we find and install it quickly). can we switch from it to dovecot smoothly? or we have to convert the maildirs somehow?
- I've got a few plan in my mind it it possible to do it with dovecot
now or in the near future (if yes what is the estimated time)?:
- authenticate from LDAP, the best would be trough PAM?
- use the same user with different domain. eg: lfarkas@bnap.hu, lfarkas@bppiac.hu with the same imap server? handle more domains.
- use imaps and use Digest-MD5 and/or CRAM-MD5?
- put a database backend under imap and store the mails in a database.
- use WITHOUT local users? it's very important! most case a user never ever log into the local system and I would not like to put them into /etc/password.
- do it all the above at the same time!? thanks.

Dovecot works fine with Courier. We were using both simultaneously for months. Message UIDs aren't shared though.
I don't have much LDAP plans right now .. PAM would likely already have existing LDAP plugins, but you'd also have to keep the users in /etc/passwd then (without passwords).
Authentication issue mostly, with plain authentication Dovecot would just treat the whole user@domain as a username. Some other mechanisms do support realms, and Dovecot's Digest-MD5 and passwd-file support realms already.
imaps and Digest-MD5 are already there. Digest-MD5 can't work (and can't be made to work) with PAM authentication though.
I've been thinking about SQL database support from the beginning. However it'd probably be slower and require a bit more memory than with the current indexes.
Currently Dovecot supports passwd-like file where you could store the users. For example /etc/imap.passwd.
Oh, and there's also vpopmail support which should handle virtual domains and LDAP and everything. Maybe you should try that. Although it again only support plaintext authentication.
