I believe there is a bug in the mfcheck patch on the qmail Web site. I noticed a strange interaction between one of my mailing list servers and our main mail server. qmail generated a double bounce because of a problem with ezmlm (nothing major). It attempted to deliver the message to ~alias/dot-qmail-postmaster, which is forwarded to a remote address. qmail uses <#@[]> as the envelope sender on the message, but this is refused by the main mail server with the mfcheck patch, saying "envelope sender domain must exist." Now, I suppose that forwarding double bounces to a remote machine may not be the best practice, and I only do it on this one machine. However, I think that the mfcheck routine should check for the special sender address. It seems kinda silly that qmail should refuse its own "special" address, and besides that the mfcheck routine already allows <> through (yes, I know this is required anyway). I'm aware of the environment variable setting, which I will use for the time being. shag ===== Judd Bourgeois | CNM Network +1 (805) 520-7170 Software Architect | 1900 Los Angeles Avenue, 2nd Floor [EMAIL PROTECTED] | Simi Valley, CA 93065 Quidquid latine dictum sit, altum viditur.
