Folks have talked about a possible STMP extension to allow message body

erm, headers have come first since 1981, and if you don't like them
you can pass the connection off to a very lightweight thread that
sleeps between collecting single lines and eventually issues a rejection.
True, this spares your CPU but still eats your network bandwidth. If we
have to extract PRD from the headers to check against RFROM: and it doesn't
match, I guess this is the best you can do in a bad situation.
Seige tactics.
The qsmtpd list has had much discussion of the "spamcannibal" approach
in which your MTA informs your firewall to drop a random half of the
packets arriving on this eschewed connection.
Advenge does a magic phrase check on the headers as soon as they are
all in.
Sounds interesting. What can you tell us about this?
