I is using Ezmlm + Qmail. I want to have a script to check mail's source IP address ( so I want read mail's header), my purpose is to reject some IP (don't permit some IP address send to my mailing list) For instance I have a mailing list is "listname@domain". When someone send mail to listname@domain , my alias file (.qmail-listname) first check mail's source IP address.
