This is just selective greylisting, which lots of sites use as a
blanket policy.
A look at
http://help.yahoo.com/l/us/yahoo/mail/postmaster/postmaster-15.html
suggests that Yahoo doesn't have a clue about discussion lists. They
seem to think that all mailing lists are announcement lists (of course
that's apparently the OP's case). Consider this list:
Other great resources:
* Help For Marketers by Scott Hazen Mueller
* Marketing on the Internet Without Getting Burned by John C. Mozena
* ESPC's best practices
* How to Advertise Responsibly Using E-Mail and Newsgroups (RFC 3098)
* MAAWG Sender BCP Version 1.1
:-(
If you're in a hosted environment, you might think about asking your
host to implement domain keys and/or PGP-signing your mail. (Mailman
is (was?) not friendly to domain keys of non-owner posters, but in the
case of an announcement list having the host sign the post should work
fine.)
