outgoing mail from gamera

Looking into /var/log/qmail/current i see qmail is sending out mail to some server for sure we never send to.
How is it possible ?
It seems gamera is acting like a sender mail even if it should send only to servers listed in /var/qmail/control/smtproutes

It seems.
It seems these bastards are sending out using fake email address.
gamera is sending back failure notice and the sistems fails under hundreds email.
As i know there's no way to prevent gamera sending out failure notice, correct?
I suppose it is a common problem.

yes i know.
the problem can't be fixed by spamassassin because of many relays.
Then the last change is bouncecontrol that, as i see, is still in progress.
I dare to say that failure notices are at this point completly unuseful and all mailservers should allow to block them by default....i hope they will.

The source rpm for qmail is right here:

It sounds to me like you guys care enough about the problem to perhaps take over as maintainers for this package? That would help me to no end, because honestly I do not have the bandwidth to work on it any more.

I care about not sending out backscatter, but having looked at qmail I don't have the feeling it's an easy beginners package to hack on. I think I may just migrate our fallback MX over from Project Gamera to something based on Postfix or something.

Follow up on this one. You'd have the exact same backscatter problem with Postfix. The only way to do what you're talking about with it is to have a list of valid users on the the smarthost (qmail, postfix, exim). The only difference is that there is a native feature in postfix for that list, and with qmail you'd have to use a version patched to support it ( like this is:
http://3es.atomicrocketturtle.com/packa ... rt.src.rpm)
I havent found an MTA yet that lets you turn off failure notices completely. Have you run across any patches or info about it?
