It's not. I've never seen Mailman hang like that in more than 4
years, with versions 2.0.13 and 2.1.5.

It's probably the one listed in smtp-failure, see below.

True. But that's not the kind of "junk" that causes problems for
Mailman; Mailman will disable delivery or unsubscribe addresses that
become invalid. The "junk" that causes Mailman to blow up are
syntactically invalid (eg, contain illegal characters) and must be
introduced by the list admin using "mass subscribe" or a command line
tool. If you've never done that, ie, all your users subscribed
themselves, then you will have no problematic junk addresses, just
undeliverable ones that will be automatically weeded out.
In your earlier message you provided this log:
smtp-failure:Apr 24 07:39:11 2005 (26501) delivery to
<removed-email-address> failed with code -1: please run connect() first
While it's possible that there's a connect() function in Mailman that
Mailman is failing to run, that seems very unlikely ... we would have
heard about it by now. There is a connect() function in many OSes,
for the "socket" interface layered over raw Internet connections. It
seems quite possible to me that your OS or network is hosed, resulting
socket connections appearing to be internally broken, and Mailman
being unable to connect to a remote host for long periods of time. In
that case, it might very well hang assuming that it should keep trying
until the network admin fixes whatever the problem is.
As far as I can tell, Mac OS X sometimes wedges itself in this way.
An SSH connection will simply go away ... until I connect to the same
host in a separate connection. Then the shell will come back up, the
X tunnel will start working again, etc, etc.

Waiting a bit and upgrading to 2.1.6 (due out real soon) might (or
might not) be a good idea.
However, if my guess that the smtp-failure message is coming from the
OS is correct, upgrading Mailman is not very likely to fix it.
