Please note that if you implement this, you have the potential to block a *lot* of legitimate e-mail. For example, this e-mail is coming to you from the redhat.com domain, yet it's got my From: address on it. It's quite possible for a legitimate user to send e-mail from a different domain. Even if I sent e-mail directly to you, I've got a SMART_HOST defined that will send it to you via my ISP, yet keep my ewilts.org From: address (and I host multiple domains on my home server). -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
