There are a lot smarter people than me on this thread that will speak up if I am wrong, but as I understand it, I *believe* this would work for what you need.
Add a line into your rules.ima T~localdomain!AND!F~blockeddomain:!BOUNCE! i.e. T~microsoft\.com!AND!F~sun\.com:!BOUNCE! If you edit the rules file for the one local domain you host that wants this foreign domain blocked, you could eliminate the T~localdomain!AND! part of the rule. If you are going for redundancy and double checking, you could also include the foreign domain mail server IP(s) from their MX Records: T~localdomain!AND!H~x\.x\.x\.x:!BOUNCE! i.e. T~microsoft\.com!AND!H~192\.18\.96\.3:!BOUNCE! I believe this should bounce the email back, although it will show the IMAIL bounce rule and thus "alert" them that your local hosted domain is blocking their domain, not simply a failure notice as if it could not get through. Probably the only way to do a complete block before it hits the IMAIL Server is if every domain you host is on a separate IP and you block incoming Port 25 of the IP of their mail server at your router on that single IP. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of David Dodell Sent: Friday, October 10, 2003 8:38 PM To: Imail Mailing List Subject: [IMail Forum] blocking a domain I have a domain I want to block ... I know I can put it in the "Kill File" in the SMTP security section. However, I act as a primary MX for several domains that want to receive mail from this domain. Anyway I can selectively block mail from this domain going to certain domains that I host, but allow it to pass through on others where I'm just a mail relay? Strange situation, I just don't want to filter and delete, I want to refuse so the sending domain gets a refused connection and failure in their logs / email bounce.
