At my university we are trying to implement a distributed email backend,
but I have some troubles,
The topology:
Server A: Postfix+LMTP # MTA
Server B: Dovecot+LMTP # Just mailboxes
Server C: Dovecot # POP3/IMAP
Right now the Server A can leave a received email to the Server B, but I
don't know how to communicate Server C to the Server B to retrieve the
emails.
I think that we should use IMAP protocol, but I am confused about how to
connect them, I don't know if we have to use a proxy IMAP server, or
another thing.
It all depends on what you want to accomplish...
First, I'm guessing your subject is not precisely correct - the IMAP
server IS 'the mailboxes'...
So, I guess you meant separate MTA and IMAP servers?
If so, then...
a) you could set up dsync to sync server C with B
b) you could do the same with imapsync (best to use dsync though, unless
you're stuck with dovecot versions prior to 2.2.# due to brain-dead
distro limitations or corporate policies)
c) you could use some kind of distributed filesystem
Why the 2 dovecot servers? If it is for load, how many users on each
(maybe you don't need 2)? If for redundancy, then definitely dsync, but
there are other issues to consider (if HA is your goal)...
