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. Yes I read about infinite loops and logic behind empty from ================================================== Pavel Ganelin tel: (703)-444-6750 x 231 MarketSwitch Corp. fax: (703)-444-6812 ==================================================
