Hmm. Looks like when I responded to the original requestor late last night,
the list didn't cc'd. For the benefit of the archives relating to the last
question above:

FAQ Q0021 (in the Exim 3 FAQ) comes into play here I think. Personally I've
had some success with setting DELIVER_OUT_BUFFER_SIZE low as suggested in
the FAQ but YMMV. However the better solution, if possible, is to convince
the remote site that MailGuard is a PoS and should be turned off.
