uhm... on a second thought.. the delay isn't needed
I mean...
* ASSP receives a connection request
* The connection is accepted
* ASSP, before proxying the connection to the local
mailserver, checks if the external host already sent
something; if so, the connection is dropped
* optionally the same check may be applied to the
MAIL FROM/RCPT TO/DATA commands; if the
remote host doesn't wait for the server response
then it's considered an "early talker" and the
connection is dropped
* in either case, early talkers connecting/retrying too
often may then be penalized using the PB
Also, implementing the "early talker" check inside the
same function performing the HELO check may ease
adding such a function to ASSP, and limiting the check
to the HELO phase should possibly ease the coding
of such a function
