Why would that be? My email comes from within my network, which is what it says on that recieved line. Does it not make sense that if I recieve mail from an IP Address that postfix says, that is from a LOCAL user but not from the LOCAL network, so reject or silently drop it. I have this problem when I run the mailing list as well. Forgies get through when I'm on the list so I resort to using an outside email address to get mail from mailings lists i run inside my network. I definitely want a policy that outright rejects any email addressed FROM a local user that doesn't come from inside my network, and the 10.0.0 private range behind my router. If your saying that email from an external mailing list that has me on the From ithe second line is dropped, that is OK. I have my sent emails. > There are better ways to block forgeries.

I'm getting to be an old man and I'd rather drink scotch and watch the playoffs ;) I already have a huge stack of Artifical intelligence theory to read and to learn CLIPS et al because at 52 years of age decided to go back to school.
