Mail list problems.

[Minnesota Slinky]

Hello all,

When I try to send messages to the list via my own
mail server, I'm getting the following error (in
/var/log/maillog):

Anyone have any ideas what I need to fix?  Reverse DNS
lookup of IPs is provided by my upstream provider, in
this case Qwest.  That IP should resolve as
front-door.secure-computing.net.

Thanks for you help.

P.S. This just started happening a day or two ago,
after an attempt to install cyrus-sasl, which has to
do with the messages that aren't getting through.
