When you see some actual disabling bounce notifications, you will
hopefully be able to answer that for yourself. Until then, I don't
know what causes it.

Mailman handles large lists and large volumes of mail just fine with
appropriately sized hardware and properly configured MTAs. See the FAQ
at <http://wiki.list.org/x/NoA9> and note the following quoted from
the end of that article.

   If you're going to be running lists with more than a few thousand
   members, then you need to have a thorough understanding of how your
   MTA and Mailman work, and a deep and intimate familiarity with
   Internet e-mail in general. And of course, you will have to
   carefully consider how best to tune your MTA and Mailman to work
   best together. If you're missing any of these prerequisites, you're
   in for a difficult time.

Increase your disk storage. These days, when a 500GB drive costs well
under $100 US, a production server with 10GB of storage is way too
cramped, and your lack of disk space is causing you do do all sorts of
questionable things that shouldn't be necessary.
