[Dovecot] doveadm director status username != doveadm director status username at mailserver

[Joseba Torre]

Hi,

I've almost finished my new director based setup, but in the first test 
I discovered that imap and lmtp connections were not always being 
proxied to the same server. After some research now I think that the 
main problem is that in imap connections users connect as 'username' 
while lmtp connections are as 'username at mailserver'.

In my current setup I receive mail via SMTP in my director servers 
(which are loadbalanced by a CISCO machine), and then they send them to 
dovecot running on localhost. I've tried to get rid of the @mailserver 
in postfix in a generic way with no success.

Is there any way to redirect connections based only in the local part of 
the address? Or there is a way to get rid of the @mailserver in the 
postfix -> lmtp connection?

Both doveadm config -n and postconf -n are attached.

Thanks.
