(OT) anti-spam blocking

[Bill Campbell]

I got another message forwarded to me today saying that somebody can't send
to filepro-list at celestial.com because their ISP is being blocked for
spamming, and to please unblock them (Comcast in this case).  Checking the
IP in question turned up the usual amount of spam to ancient spamtrap
addresses which are what caused the blocks to be added.

The simple solution to this is to send messages directly to the system
running Mailman at filepro-list at lists.celestial.com.  This machine doesn't
have our most draconian anti-spam blocks in place.  This server uses only
major DNSRBLS including a couple from spamhaus.org.

Be aware that if your e-mail server doesn't have any reverse DNS (rDNS)
configured, it will be rejected.  Configuring rDNS is absolutely basic, and
any ISP that doesn't do it is going to have serious problems.

One man's brain plus one other will produce one half as many ideas as one
man would have produced alone.  These two plus two more will produce half
again as many ideas.  These four plus four more begin to represent a
creative meeting, and the ratio changes to one quarter as many ...
