Hi,

I'd like to achieve the following setup whit dovecot using multiple servers :
- one server dedicated to all client IMAP (TLS) connections (imap.mymaindomain.com, see below )
- each backend server has it's own local storage. no replication
- each backend server responsible of a few domains
- each backend server has it's own Mysql local database for user's passwords.

                                                       ===> Server 1 : domains A, B and C

====> imap.mymaindomain.com  ===> Server 2 : domains D, E and F
             (143 TLS / 993 SSL)
                                                        ===> Server 3 : domains G, H

For example, if a user connects from domain E to imap.mymaindomain.com, will Dovecot be able to use password database hosted on Server 2 ?

Thank you !

Alex
