Imap mirroring

#1 06-09-2008, 06:21 AM

Hi,

I'm managing an email servers postfix+courier-imap, and i would like to
have an off site mirror of it, which purpose is to serve as a webmail
with roundcube.

Do some one know a way to have all accounts synchronized, mails,
read/delete flags, etc, in almost real time ?
The two servers are separated by internet, onsite one should be master...

I'm not very sure that imap is the best way to do it.

Any help is welcome

Have a nice week!

The only way to do it would be with some kind of a distributed filesystem.
AFS comes to mind, but that one is rather difficult to set up. There's no
good way to do this purely in application software.

OK, thanks a lot, the more I thought the more I headed toward this solution.

Cyrus supports replication, though it won't do all of the jobs that
you listed.

I know nothing about Macs and their software but do use this on Linux to
mirror my FastMail IMAP account to a local directory:
