Please excuse my blunt language, but what you suggest is dumb, broken, and a malicious attack on a fundamentally necessary property of SMTP. Far better would be to either (a) block reception of mail from the broken site, which eliminates the need to bounce messages to them, or (b) write a patch to qmail-send or possibly qmail-remote so that it simply discards bounces which would go to that site. And always - educate, educate, educate. -- Jeff Hayward On Mon, 1 Nov 1999, Pavel Ganelin wrote: I looked through a lot of E-mail qmail archive discussing it, but I did not see any solution. We have domain A and run qmail-smtp server to relay E-mails for domain B. When a user X from domain B sends a message to the wrong address using our qmail server The messages bounced and qmail sends a message to X@B with From: <> The SMPT server on B refuses to accept it (null from, spam filtering in action I assume) and it ends double bouncing to me as postmaster@A. I saw a lot of messages that I should mail postmaster@B a copy of RFC :-) but I think it is useless, because B is a big ISP provider and they would not change anything in their configuration for us. It there any way in bounce message insert something like bounce@A without patching the code (i.e. using some configuration files?). Qmail has doublebounce files no "singlebouncefrom" PS.
