Continued mail server problems for all PGSQL mailing lists I'm on

I'm actually getting the mailing list mail, so I don't know what the deal is.
Successful deliveries are coming from 64.117.225.209.  But 207.173.200.206 has
big problems.  Sendmail is misconfigured in at least two ways.  DNS is not
even configured at all for reverse DNS.  I can't whitelist the sender email
addresses because spammers already use them.  I can't whitelist the IP address
because you guys keep changing them.  I can't whitelist the server domain
because the reverse DNS isn't set up yet (it takes me less than 5 minutes to
set that up).  I'm sure the list operators are experts in PostgreSQL.  I'm
not.  But at least I don't pretend to be.  Maybe you should ask some experts
in running mailing lists, mail servers, and DNS servers, to give you a hand.
