Are you suggesting that we configure our e-mail servers to notify people upon automatic deletion of spam? Frequently, spam cannot be properly identified until closure of the SMTP conversation and that final 200 mMESSAGE ACCEPTED...or do you think that TCP/IP connection should be held open until the message can be scanned for spam and viruses just so we can give a 550 MESSAGE REJECTED error instead of silently dropping it?
You can reject right after DATA, at the <CR><LF>.<CR><LF> stage, before QUIT
That's still an in line smtp reject rather than an accept + bounce DSN.
Exim with the spamassassin patches (sa-exim) does this, for example.
-srs
Of course Postfix can be setup (using spampd) with spamassassin to do exactly the same. I believe Sendmail+MimeDefang+Spamassassin will also reject inline if set to do so. Regards, Mat
