Re: [Dovecot] Proxy to join two accounts

I have server with IMAP on dovecot for user mails and second server on archiveopteryx as mail archive.

I'm wondering if it's possible to make some sort of proxy to these two servers in way where:

• dovecot server will be main IMAP service with INBOX, etc
• I want archiveopteryx account to be something like shared folder with read only access (no delete, no move, etc) in path ex. /archive/user.name
• this proxy mappings should allow adding few archive accounts to one user (in case of people replacement)

• it will be cool if this mappings could be defined in database so I could write tools to manage archive access for bosses.

Is such case possible to achieve with dovecot (any howto or example would be very helpful)? If not - do you know any proxy tools that could allow such configuration?

You should be able to implement something like that by creating a new namespace with location=imapc:

http://wiki2.dovecot.org/HowTo/ImapcProxy and http://wiki2.dovecot.org/Migration/Dsync have some information about the imapc settings.

ACLs are a bit more difficult though, since currently there aren't any "default ACLs".
