[Mailman-Users] mailman forwardedmail is delayed from 45-hour?

[admin2]

HI,

mailman list mail is really delayed on my box at the moment

a dual pentium
running FreeBSD 4.7 Stable
running send mail 8.12.9 
mailman version 2.1.1

I am seeing lots of hostmap failues in my sendmail queue.  is there anyway to
increase the speed of delivery even though these host map errors could be
creating sluggishness.  What else could I look at?
