Howdy, Is it possible to restrict certain entries in /etc/aliases to only allow usage when the sender email address is @mydomain.com? In my case, I have the 'group' sales@ defined to go to all our sales folks by using one entry in /etc/aliases: sales: [email protected], [email protected], etc. What I want is to disable anyone not claiming to be from @domain.com from also using my group since it seems impossible to get my whuffo's to consistently use the BCC field to hide the group name. The spammers of the world pick up on my groups and quite efficiently send all my folks spam using the convenient group names I have provided them. Certainly I know that the source email can and will be faked, but most of the time the spam sender doesn't fake it @mydomain.com.
Does anyone have a good idea how to do this? Sorry for the possibly off topic email, I tried hooking up with sendmail.org's forum and failed miserably. With the known brilliance within this group, I am confident that someone here knows more about their stuff than they do. Perhaps the answer will also help others here? Thanks in advance, Bill Watson [email protected] _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
