[Dovecot] Dovecot+LDAP lda problem

[Zeljko Culek]

I'll try to simplify to be more understandable:

I have a mailing group (or list if you prefer) e.g. developers at nth.ch. 
This group has many recipients, defined with LDAP attribute 
maiForwardingAddress for developers at nth.ch. Those recipients can be both 
internal (nth.ch) and external (any other domain - gmail, yahoo, etc.). 
So, when mail is sent to developers at nth.ch, it is delivered to all of 
the recipients in mailForwardingAddress, but also to developers at nth.ch 
mailbox; with qmail, that mailbox didn't even exist, i.e. mail was 
delivered only to mailForwardingAddress recipients, and no 
developers at nth.ch mailbox was created or deliverd a message.

So, that's what I want to achieve - mail to be delivered only to 
mailForwardingAddress recipient mailboxes. So, deliveryMode=nolocal with 
qmail meant - don't deliver mail to mail=something, only deliver to 
mailForwardingAddress=something.
