My guess is that you're doing DNS validation and other anti-spam checks on 
your outbound mail.  You don't want to do that.  Do those things on input, 
and then set up a separate outbound-only mail processor that avoids all of 
those checks, because you've already done them on input.

See FAQ 4.20 at <http://wiki.list.org/pages/viewpage.action?pageId=4030587>, 
and the stuff in section 6 that are specific to your MTA, and also pay 
special attention to FAQ 6.6 at 
<http://wiki.list.org/display/DOC/Mailman+Performance+Tuning+for+Mail+Delivery>.
