[Dovecot] problems with folders in another server (2nd. issue)

[Jose Luis Faria]

Hello Timo,

I'm using qmail-LDAP in cluster with 2 servers:

mx1.di.uminho.pt and mx2.di.uminho.pt

the email cx1 is on mx1 and I want to get access using both servers.

dovecot-ldap.conf.ext:
...
pass_attrs = uid=user,userPassword=password,=y=proxy_maybe,mailHost=host
...

every user on LDAP have the attribute

mailHost=mx1.di.uminho.pt

or

mailHost=mx2.di.uminho.pt


dovecot_debug.log:
