It's not our DNS the one that's wrong, but that of a company we're trying to send a mail to. I've already talked with them a couple of times over the phone and am still trying to convince them that their DNS configuration is not right and that they should fix it, but trying to convince another company that they're doing something wrong is not always easy... Incidentally, we're on the same city just a couple of blocks away, I'm starting to think maybe I should go there and fix their DNS for them. :-/ The point is that, even if this DNS setup is wrong, other mail servers (google, hotmail, yahoo, and many others) deal with it without problems and send the mail to [EMAIL PROTECTED], while qmail changes the original domain (domainA) for the one the CNAME is pointing to (domainB) and the delivery fails because the user [EMAIL PROTECTED] doesn't exist. Don't get me wrong: I know that qmail is not at fault here but this ill DNS configuration. I just find it odd that every server out there but qmail seems to handle this DNS setup right. -- Vicente Aguilar <[EMAIL PROTECTED]> Departamento de Sistemas Tlf.: 965 98 71 92 Recursos en la Red, S.L.U. http://www.renr.es
