> When I first saw the SA, I marveled, why SA cannot delete the mail. SA
can't delete the message. The possibility of the message deletion
depends on the MTA you are using. If you use procmail for local
delivery, you can teach the procmail to delete the message, if you use
other program, you must teach your program to delete. :(

not?

No, it wouldn't.

Imagine your SA is configured to work together with your MTA, be it
'exim' in this case. exim receivies a message, and gives it somehow to
SA. SA now "deletes" it - the only thing SA could do is throw it away
and tell exim about it. But it's up to exim to care for the mail, it's
exim maintaining the spool file and doing the delivery, not SA.

So, SA does a pretty good job by givng a modified mail back to exim and
tell exim wether it's spam or not.

There's one slight exception from the above: You may configure certain
MTAs to let SA jump in at SMTP receive time and reject the message
before it has been accepted in its whole or even teergrub the sender.
The former is close to "SA deleting the message", although it's
nevertheless the MTA actually doing it. But because they work so very
close together, you could get the impression that SA does the job. SA
still flags the mail only, but the MTA reacts in the same session and
quite immediatly, that's all.

You may substitue the term 'exim' with one of 'postfix', 'sendmail',
'Qmail', 'smail' and the like.
