Hello All, If I have missed an earlier post, I apologize but I have grep'd the archives and did not find my answer. First let me state that sendmail is accepting connections from external interfaces and I am receiving all of my sites mail AFAIK. The question is "How do I change the default sendmail.mc file to allow external local machines to relay mail through my mail gateway?" This has only become a problem since a fresh install of RHL 9.0.... and is probably something really simple that I have just overlooked but I am stumped. TIA :) Ron
