So where does the SPAM go if the tick is not checked?
If it scores above your threshold in simscan, then it goes to
/dev/null
I hate to nit pick, but to be more accurate I believe it's rejected
as spam. In any case, the recipient can never see it.
Who are you kidding about hating to nit pick?
Technically, the copy that was received is delivered to /dev/null and
an error message is sent to the originating server notifying them
that the message was denied as spam. The SMTP session remains open
during the simscan phase.
I'd really like to be clear on this, so I understand the inner workings.
My understanding is that yes, the SMTP session remains open during the
simscan phase. If the score is over the threshold in the simcontrol
file (spam_hits=n), then the message is flat out rejected, and the
sending server is notified as such before the smtp session terminates.
The message is never received (successfully), nor delivered to
/dev/null. The sending server subsequently bounces the message back to
the sender.
Please correct me if I'm wrong on this.
It has to get a copy of the message to scan. It does not return a
successful delivery command to the sending server until the scanning
process is complete (the remote server thinks the receiving server it
still receiving the message). If it fails any of the tests, a SMTP
message is returned to the originating server and the copy of the
message that the server did receive (to scan) is discarded - this is
done before the SMTP session is closed.
The originating server usually bounces a message to the sender, but
since this is controllable it's hard to say what a given server will do
with a bounce.
Ultimately it has to get a copy of the message to scan, but leaves the
SMTP session open so that it may return an error code (clarification: an
error code is anything, even a successful code). Once it has decided to
do something with the message, it still has to do something with the
copy it got to scan.
