Hello
We have two different servers. They both use the same spam gateway. One does not receive an error when sending an email to the other, but the other one gives the following error when sending an email, even though the domain is not in it.
What could be the problem?

Re: same antispam problem
Sounds like you have a mail loop occurring in that direction somehow. I'm not sure why with the information you provided. You may need to check your /etc/postfix/transport file and see if it makes sense for both servers.

I checked. I looked there first. There is no confusion.
