Sorry, your email was moderated as a new member.

It seems you’ve been doing some work on this, and had partial success. But, I’m not clear on what the problem is.

You’re trying to get SRS sender address rewriting. You’ve got it working for some emails, but not others. Can you explain more clearly which addresses are not being rewritten? Is this router (below) the only relevant part of your configuration?

Do you have debug output that proves that the router is actually being called? It could be that an earlier router is handling the email.
