If you would like, I can post a *really* nice set of rule sets, which will allow you to specify a (group of) host which can relay through your system in the format of Class A,B,C or individually. All the rulesets that where listed in the sendmail pages required you to individually list each host! (a pain in the ***). Another really nice ruleset is the DNS lookup one in which the RCPT address must resolve ;) Seeya stavros@esc.net.au
