dovecot - May 2007 - connecting postfix with dovecot trouble

Hello listmembers,

we have some trouble connecting postfix to dovecot. 
after a lot of hours the transport and delivery is
working but dovecot can't get the correct user.

postmap -q some.user at domain.com ldap:/etc/postfix/ldap-aliases.cf first
returns: someuser 

The mailbox someuser exists and i can login with this
user on imap and i can deliver directly using deliver -d
but on mail delivery thrue postfix dovecot is not looking
for someuser. It looks for someuser at host.domain.com.

It seems that postfix or dovecot appends the hostname to
the mailboxname. But i cant figure out which of both.
If i change the uid to someuser at hostname.domain.com on
ldap-server anything works fine. how can i fix this?

i dont know if anyone needs config files for diagnostic.
if so - please tell me and i post the needed informations.

best regards

Since your ldap query is returning only 'someuser', Postfix is rewriting
some.user at domain.com to 'someuser' (since it's an alias), and
then
adding its hostname as the @domain part. See here for more detail on that:

http://www.postfix.org/postconf.5.html#append_at_myorigin

Your ldap query needs to return the address that you want to pass to 
deliver. So, I'm not sure from your email what address you want deliver 
to be given, but I'll guess that it should return 'someuser at
domain.com'
instead of just 'someuser'. If you are trying to pass deliver just 
'someuser' you may need to jump through some hoops in your postfix 
configuration... you're probably better off configuring dovecot to deal 
with a full email address.
