[Dovecot] allow_nets and local sockets

Hello,

i am running dovevot 2.0.5 using ldap authentication with the allow_nets paramter to limit access to some local networks. The problem is, when i want to use the local lmtp socket from postfix

*virtual_transport = lmtp:unix:private/dovecot-lmtp *

i get the follwing error:

*Oct 21 15:48:03 auth: Info: passdb(username): allow_nets check failed: Remote IP not known

*When using the TCP socket with postfix

*virtual_transport = lmtp:localhost:30025

*it is working. (i have 127.0.0.0/8 in the allow_nets list)

Is there a way, other than using two different config sets to get this working together ? Something like disabling the address lookup on local passdb sockets ?

Regards, Oliver
