SMTP works on port 25. Port 113 is identd, and has nothing to do with SMTP. The only issue is that when you send email, the receiving SMTP server *might* do a reverse ident lookup on your connection, and if you're blocking it, it can cause your outbound SMTP connection to be delayed by 30 seconds or so. If you really want to block it, then use a REJECT target. -- Anand Buddhdev http://anand.org -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
