[Kolab-devel] [issue3610] Mail to unknown at something.example.com gets accepted and yields kolabmailboxfilter exit 38

[Thomas Arendsen Hein]

New submission from Thomas Arendsen Hein <thomas at intevation.de>:

Kolab Server 2.2.1:

Mail from localhost (via telnet/nc) to unknown at example.com correctly gets
rejected with
550 5.1.1 <unknown at example.com>: Recipient address rejected: User unknown in
local recipient table

But when sending to unknown at something.example.com (probably) the
masquerade_domains feature kicks in and the mail gets accepted and passed to
kolabmailboxfilter which results in a bounce and postfix logs:
(Command died with status 38: "/kolab/bin/php". Command output:   )

/kolab/var/kolab-filter/log/filter.log contains:

The last block is for the bounce message,
fatal.log does not show any new messages.

Despite the unsuccessful exit there is no indication of a problem in the
filter log!

Besides the filter problem I think that even with masquerade_domains the mail
should not get accepted, I'll look into this part.
