Kevin, Yes, I was referring to port 587. I think you and I are saying the same thing but I'll try to clarify for everyone reading this topic. Smartermail does not support port 587 as a submission-only port as defined by the RFCs. Smartermail supports defining a secondary SMTP port. You could configure smartermail to accept smtp connections on both port 25 and port 587. Unfortunately, that doesn't solve anything because we need port 587 to be a submission-only port and to require SMTP AUTH. The latter is the only means we would have to keep spammers from bypassing your front-end spam filtering gateway server. If they find that smartermail accepts smtp connections for delivery on port 587 and that it doesn't require any kind of authorization they will just dump their spam there and bypass the gateway server altogether. Smartertools has said they will consider changing it for version 3 but they say that about everything and they also have no plans in the near future to release version 3. They are working on their stats software at the moment. I personally have concluded that the only really practical way to spam filter is with a spam filtering gateway up front in order to off-load as much work as possible from the mail server. I'm searching for solutions. I've been using ASSP which runs as proxy but we're getting a lot of false positives with it. Declude Pro is too expensive even with the smartertools $100 discount we receive. --- This E-mail came from the Declude.JunkMail mailing list.
