I have an announcement list with 45,000 members, when I send an email not only does it severely overload the server but it also gets blocked from performing DNS lookups after the first few thousand lookups.
It has been suggested that I set up a caching DNS server but that doesn't look as easy as it sounds and I already am using bind so I would prefer just tweaking that installation to do what I need if possible. Looking on the internet it just isn't clear cut how to do this, especially in a way that isn't going to mess with my current setup which is a typical Redhat Cpanel setup hosting a fair amount of sites.
What have other people done in this instance?

Which MTA are you using? You may want to let mailman send it all to the MTA and have the MTA slow the delivery. Postfix has some rate controls (http://www.postfix.org/rate.html), I assume that most of the other MTAs do too.
Or, I may be nuts :-).

I am using the default Cpanel/exim configuration on redhat.
