Although the fake-MX was discussed I think the discussion included a caveat that if you are going to use a fake-MX you need to use it for an IP address that is allocated and is controlled by you. Otherwise you open up the potential for real mail to do very strange things!!! Use of a BOGON address might have been an idea, as long as it wasn't a BOGON that had special uses (e.g. RFC1918), however, there are no such BOGONs left anymore... the last allocatable IPs were given out this very week.That's an interesting point of view. It was suggested on this list fairly recently to publish a fake secondary MX as a way to reduce spam. The stated reason being that some spamming software hits the backup MX first and if that doesn't work will give up without trying any others.I realize that can be done without using a 127 or RFC 1918 address, but some people are doing it that way.Out of curiosity, did you start blocking those because you saw that as a pattern in spam email or is it more a matter of principle?
