Problem

A Forum reader recently asked:

"We have two servers: "grpwise" (a GroupWise 7 internal mail server) and "filter" (a Postfix smtp antivirus and spam filter for incoming mail).

We're running SpamAssassin on "filter". SpamAssassin allows spam or ham messages to be forwarded to local delivery accounts on "filter" for manual training. For example, users can send good mail to "ham@filter.mydomain.com", and bad mail to "spam@filter.mydomain.com" to retrain SpamAssassin if needed.

How can this be configured? We get a "550 Host unknown" error when mailing to these addresses internally via a groupwise client. Is this just a DNS issue, or will a parameter need to be changed in the GroupWise system? I'm new to GroupWise."

And here's the response from Danita Zanre ...

Solution

It's a DNS issue, and your best bet is to create a route.cfg entry to fix it.

1. In the domain/wpgate/gwia.cfg, edit (or create) the route.cfg file and put this in:

filter.mydomain.com [123.123.123.123]

2. For the IP address (and you need the brackets), put the private IP address of your postfix server (I'm assuming that's where you are trying to send them).

3. Restart the GWIA.

Now any mail destined for filter.mydomain.com will be passed without a DNS lookup to the IP address you have specified.
