My main box at home runs FreeBSD and is configured to use local sendmail for outgoing because some of the other lists I subscribe to used to bounce my messages due to brain-damaged ISP not having reverse DNS for their mailservers, while reverse DNS on their dialup and DSL accounts works. �This makes me a "dynamically addressed port" which _is_ a source of "legitimate authorised SMTP connections." �Or so I would think, since those lists stopped bouncing my messages after I switched to my own sendmail. I have always thought that blacklisting ISP dialup etc. ports was a bad idea -- those not running Windows are often prevented from using all the services their OS provides due to attempts to block spam. �I am responsible for disposing of the junk snail mail I receive and I consider that more of a pain than setting up filters on my BSD box and basically forgetting about it, while the number of messages in my trash can each day tells me that external spam-blocking attempts aren't working very well. I personally would rather see a spam hit a list occasionally, rather than have a legitimate user post bounced and followed up by a post asking why which starts a thread about the whole thing again. That can be a worse hit on signal-to-noise ratio than the spam itself.
