[Mailman-Users] MX lookup failures blocking queue

Hi all,

There seems to be a little DNS weirdness going on today -- a couple
domains used by subscribers to my list can't be looked up.  Their local
nameservers are timing out, so mailman is logging errors like so:

     Can not check MX records for recipient host

Now, it's understandable that this would prevent delivery to the
individual subscriber, but it seems to have blocked up the list entirely
-- messages have been piling up in the queue since yesterday.  My other
lists are still working fine.

Is it normal for one MX lookup problem to botch the whole message?  Is
there anything to be done short of unsubscribing those people until their
ISP's get the problem straightened out?
