Hi!

I am looking for a tool that does a true two-way synchronization (synchronization of expunges/deletes) of IMAP mailboxes, kind of a mixture of unison and imapsync. Does anyone have any ideas how to accomplish that?

I use OfflineIMAP [1] to sync my 2 remote IMAP accounts to with my local dovecot. Works really well.

Ah, thanks for the hint! Are you using any special offlineimap settings?

Nothing special. But here it is in case you want to have some config you can base on. I sync 2 different imap accounts to my local dovecot, where I have two virtual users (using /etc/dovecot/passwd), one per account.

--8<---------------cut here---------------start------------->8--- [general] accounts = Fastmail, Uni ui = Noninteractive.Basic

[Account Fastmail] localrepository = FastmailLocal remoterepository = FastmailRemote quick = 0

[Repository FastmailLocal] type = IMAP ssl = no remotehost = localhost remoteuser = fastmail remotepass = XXXXXXXX maxconnections = 2

[Repository UniRemote] type = IMAP ssl =yes remotehost = mail.uni-koblenz.de remoteuser = UUUUUUU remotepass = XXXXXXX maxconnections = 2 # Don't sync shared folders folderfilter = lambda foldername: not re.search('(Other Users|Shared Folders)', foldername) --8<---------------cut here---------------end--------------->8---

I hope that helps you to get started.
