This mail will never make it through. MIME::Tools, which decodes the
MIME messages, cannot handle a message with that many parts.
I suggest you use the -R and -M options to mimedefang-multiplexor to limit
the memory which the filter processes can use. While this will not help
with this particular mail, it will at least prevent your machine from
Using "-R 30000 -M 30000" should prevent the machine from dying while still
allowing plenty of room for legitimate messages.
