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
I believe Sendmail+MimeDefang+Spamassassin will also reject inline if set to do so.
