SPAM (on list) was:Re: classiccmp list (sort of) help requested

The growing problem with SPAM, etc.. It was noted in one of the trade publications I looked at that a very effective check on SPAM was to confirm that the stream opened up to you (on your port 25) actually did a "conversation" with the remote player. It seems that the 'bots just open up port 25 and send (spew), and ignore the responses. Kinda like 'typeahead'. If you can sense this, it quashes some stuff (so I've been told). Another tact might be to see if the sender HAS a port 25 on their machine. I suspect that the 'bot machines don't. Just a couple of ideas. Unfortunately fixes like these require a deep diving into the SMTP mailer at the code level. ob. on topic.. Sendmail is over 10 years old (maybe that is the problem!) -- Tom Watson tsw at johana.com ____________________________________________________________________________________ Have a burning question?
