Scalix Forums

Hi,

I've added the following lines to the smtpd.cfg to catch all mails to unknown users:

CATCH @interactive-net.de no_reply@interactive-net.de
RECIPIENT Log_Discard no_reply@interactive-net.de

A glitch in the user sync between our border email server and the scalix server caused a lot of internal mail loops.

After the restart (sendmail + scalix) same problem. It seems the configured smart host receives all mails to unknown users before the CATCH is executed.

Any suggestions?

Thanks
Reinhard

So you want to reject mail to unknown users? You use local-host-names in /etc/mail for that. Any domain listed here is not forwarded to the smarthost.

Hi Valerion,

I've no problem with host-names or domains. We deleted users on the scalix server. The sync between the scalix addressbook and the border email-server failed.

Any messages for the now deleted users on the scalix side passed the border email-server and were routed to the scalix server.
Seeing no local user scalix forwarded to sendmail which in turn sent the messages to his smarthost -- our border email server.
The border email server itself routed back to the scalix server thinking there is a valid user.

Consulting the wiki I've found the CATCH-Howto and changed the configuration as mentioned and without any success.
