There are two digest formats, MIME and RFC 934 (older and somewhat
less robust, but still pretty usable).  If all of the affected users
are on one, you could try switching to the other, possibly with some
loss of functionality depending on the MUAs in use and the content of
the messages.

The only other reasonable thing I can suggest is to contact
bigpond.com and ask them if you can get on a whitelist or if they're
willing to tell you about digest formats that pass their spam checker.
Usually the less competent the spam-checker, the less they're willing
to tell you about what features of your mail stream are triggering the
checker, but you might get lucky.
