Haines,
(Was I perhaps the addressee? I don't know of any other primenet
addresses on this list).
I ran into this a year or so ago and had some heated discussions with
the mail guru at Primenet. He said that it was an anti-spam measure.
This type of message means that the system won't accept mail sent from
a user's smtp server on a dial-up connection with a dynamic ip (the
reverse lookup indicates you are using one PSI's dialups.) These
apparently are often used by spammers whose MTA is configured to send
directly to the recipient as a way to get around filtering by their own
ISP's smtp server. Primenet (and several others) have filters which
will bounce such mail. Of course, I still get more than my share of
spam, but I got nowhere in the discussion.
The way around it is to forward all smtp to your ISP's smtp server (or
some other (static ip) host which is configured to allow you to relay,
but does not permit open relaying.
Methinks Big Brother is meddling a bit much here.
