I've got a rhl 4.2 box i've set up on the net which has sendmail 8.8 running on it. What I 'm using it for is ONE mailing list, but I don't want spammers using my machine as as a spam gateway. Is there any way for me to _accept_ mail from anyone but to NEVER send mail out from my system save from one account? Does anybody have any other special anti-spam reccomendations for a special case like this? I've already installed the anti-spam sendmail rpm but I can't figure out how to modify the sendmail.cf to put the check.m4 thing in there (the documentation on that one could be a little more explicit :)) \ \ / // ____ _ __ ____ __ Hard to believe, Harder to killfile! \ \/ // / \ |\ /|| | \ | | > << | | |\\ //|| ----< | | In God We trust.
