Hello,

Where I work we have have an interesting setup, we have 2 machines with mail accounts on them and both have dovecot. We would really like to centralize all the mail accounts on one machine, but unfortunately the administration has not approved it. However, if we could create the "illusion" that they are on the same machine that would be acceptable. If we have a 3rd machine, lets say called mail.example.com, could we install dovecot on it (using LDAP authorization), such that when a user connects to this machine, it then connects to one of the 2 other machines to retrieve their mail (instead of reading from /var/spool/mail). So in essence, the mail backend is just another POP or IMAP server. In the ldap directory we could have a field that says the mail location is: "imap://machine1.example.com" for some users and "imap://machine2.example.com" (Of course it dosent have to look like that, but I hope you get my idea), then dovecot would make a connection to those servers and read the user's mail. Does such a backend even exist? Can dovecot's plugin support register a mail_location backend (such as mbox:/blah/blah, ...)?
