Hey Alexandre,
You can achieve your idea setting a MySQL instance, for example, in each
one of your servers and also a Dovecot instance in each of them. Then you
can set your imap.mymaindomain.com server to be a imap-frontend that
performs a pre-auth step in the correct MySQL and then forwards the request
to the right Dovecot instance that performs the auth again.
Something like this:
- Request arrives in
imap.mymaindomain.com - Check if you host the informed domain
- Check then user domain, for example foo@A.com
- Validate user credentials in MySQL.A
- Forward the request to Dovecot.A

Hi,
I'd like to achieve the following setup whit dovecot using multiple servers : passwords.
- one server dedicated to all client IMAP (TLS) connections (i http://mail.numeezy.commap.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
===> Server 1 :domains A, B and C
====> i http://mail.numeezy.commap.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 i http://mail.numeezy.commap.mymaindomain.com, will Dovecot be able to use password database hosted on Server 2 ?
Thank you !
