Thanks for the help Norberto Meijome: However, I think you misunderstood the question. Let me rephrase it. The mail server at ahoc.net can receive mail for the domain. It's been doing this for some time. In other words, as you put it, sendmail.cw has the domain listed in it. In truth I am not sure he's using a sendmail.cw file, but that's not important. The problem is that mail from our mail server (aqua.intellilink.net) doesn't ever reach his mail server (ns.ahoc.net). The mail appears to fail locally because our local mail host believes the mx record points back to aqua.intellilink.net . I believe putting his domain in our sendmail.cw file would be incorrect because our users (assuming we have duplicate usernames) would receive ahoc.net mail. Not the desired effect. Although I don't think this is what you meant. But I think your answer helps state the problem. Our mail server thinks the ahoc.net domain is local and tries to deliver the mail locally. It bombs when it doesn't see ahoc.net as a valid domain to receive mail for. What it should be doing is sending the mail to ns.ahoc.net for processing like the MX record tells it to (or should tell it to).
