[Kroupware] Forwarding mail to unknown recipient to another server

[Ellis Whitehead]

Hello Paul,

Thanks for the info. ;)  I'm afraid it didn't work though -- came back with
the following response:

--------
This is the Postfix program at host mail.tscg.intra.
 
 I'm sorry to have to inform you that the message returned
 below could not be delivered to one or more destinations.
 
 For further assistance, please send mail to <postmaster>
 
 If you do so, please include this problem report. You can
 delete your own text from the message returned below.
 
                         The Postfix program
 
 <axel.richter at example.de>:
host /kolab/var/kolab/lmtp[/kolab/var/kolab/lmtp]
     said: 550-Mailbox unknown.  Either there is no mailbox associated with
this
     550-name or you do not have authorization to see it. 550 5.1.1 User
unknown
     (in reply to RCPT TO command)
--------

We're using a somewhat older version of Kolab: from mid-September.  The
"kolabconf" file you mentioned doesn't exist in that version, but a restart
of kolab did appropriately copy main.cf.template
to /kolab/etc/postfix/main.cf.

        mail /kolab # grep luser etc/postfix/main.cf
        luser_relay = $user at mail.arcor-ip.de

        mail /kolab # grep local_recipient_maps etc/postfix/main.cf
        local_recipient_maps =


However, I need to send the emails on to another server without changing the
email address -- if it gets changed to axel.richter at mail.arcor-ip.de, then
the arcor server won't know which company its for.

Any ideas?

Thanks!
Ellis
