The beowulf domain now publishes   Sender Permitted From  records.

Detailed information on SPF is at
   http://spf.pobox.com/
but here is a quick summary:

SPF is an advisory field in the domain name record that can
help mail receipients reject spam that pretends to come from popular
mailers such as beowulf.org.

SPF doesn't require you to do anything.  It does allow you or your ISP
to set up better spam filtering rules, if you choose.

To see what SPF "really does", run a DNS name server query on
beowulf.org and check out the "additional text" records.  There is a
record for SPF version 1:

beohost$ host -t txt beowulf.org
beowulf.org. text "v=spf1 a mx ptr -all"

This says "If you get a message from beowulf.org, it must come from
  A   the primary host for beowulf.org
  MX  the mail exchange hosts for beowulf.org
  PTR any host whose domain name ends in .beowulf.org
  -all  and no other machine

I don't expect even the slightest inconvenience from providing SPF
records for beowulf.org.  Please let me know if it causes any problems.
