Re: wanted: patch to reject mail if envelope sender isn't valid domain

[Mate Wierdl]

This may not be the perfect solution: you must use the qmail-users
mechanism.  First, put the dnsfq program in /var/qmail/bin (it comes
with qmail; it is used by config but is not installed) Then in each
user's .qmail file put

|dnsfq `echo $SENDER|awk -F@ '{print $NF}'`
./Mailbox

(I am assuming you do not know in advance the sender's bad address).
