No, this machine is the server from some users in my department but also 
the testing machine, and most users are using maildir while I use mdbox. 
After some tests, I found out that dovecot autodiscovery was the easiest 
solution for this.

No, if only 1 server is accesing a given user mailbox, you don't need 
that (and this is my case because I'm using director)

Forget this. Some days ago I changed de passdb query to allow users to 
connect using both the full mail address and the old identifier (which 
is not related to de mail address). But in my case, if I connect using 
my e-mail address director sends me to one server, and with my old id 
(that is being used by lmtp) to the other one. So I have 2 different 
server accessing 1 mailbox, and the problems are normal.

By now, I'll go back to only accept the old id.

Is there any way to tell director that old_id and joseba.torre at ehu.es 
are the same user (and should be directed to the same server)?
