Hi, We use Exim 4.71nb on NetBSD 5.0 . We are getting bombarded with spam with the from: address showing as our own domain, but the return-path and envelope-from showing somebody else (the spammer).
I attached the header below. Our domain is iaw.on.ca Is there an ACL statement that could reject this immediately. I tried a few with no success, just a lot of rejecting of good email. Thanks for nay help you can offer.
