Point taken. However although the thread is about (or was ment to) qmail-II
several people were talking about using existing patches and doing stuff
now.
Let's move it back on track.
*If* Dan is to do anything about pre-accept rejection of SMTP messages then
it should most definately NOT be using a control file ala badrcptto or
suchlike.
The smtpd will have to know wether a rcpt to: address will be locally
deliverable or not and reject immediately. How Dan does it is really up
to him, he's infinately better at program design than I.
I'd see it working somthing like:
qmail-smtpd-accept -> qmail-smtpd-checkaddrs -> qmail-smtpd -> ....
qmail-smtpd-accept would accept the SMTP conversation up until the DATA
statement (so it knows that all rcpt to: statements are received),
then pass all data into checkaddrs which would be a custom prog much
like checkpoppasswd (i.e. you build in your own badmailfrom, badrctpto, etc
checking). If checkaddrs doesn't like any address is can print some error
message and exit, else normally it'll execvp qmail-smtpd an carry on.

There aren't many machines come with qmail installed either ;-)
