After another 240 messages that had to be checked in the spam filter
this morning, it occurred to me that most spam has one thing in
common:

A SINGLE Received: line. The one added by your SMTPSRCV....

This because spammers need to send their spam DIRECT TO YOU from their
dial-up/cable connection to prevent detection of their activity by
their ISP (by passing their spam through the ISPs SMTP server).

Have a look. I suggest over 90% of spam is in this category.

I believe we would be able to block this type of spam readily if
SMTPSRCV could/would:

1. returns a 550 error, user unknown, or some such where no second
Received: line is encountered.

2. and/or adds the originating IP address to a timed black list so as
to reduce the load on our servers by simply not even talking to the
spammer again (for some (configurable) time at least).

What do you say Klint? Is this achievable?

I look forward to the comments from Klint and the list.
