[Mimedefang] Removing attachments with special encoding in filename

Just joined the mailing list as I've installed mimedefang today and am
just getting to grips with it. So far all is working well - ClamAV
integration is working well, as is SpamAssassin. I am using the template
config provided with the RPM on EPEL, with just a few minor tweaks to
enable ClamAV support, and add to the Subject line when SPAM is detected.
I have one query about blocked attachments. I've been running this test
This sends a set of 7 e-mails which have various reasons they should be
filtered. The first 3 pass absolutely fine, but the remaining 4 all slip
through the net. They seem to rely on doing things like special
character encoding in the filename - for example:
Or even putting the attachment inline with the message.
I've been playing with the filter definitions but so far I am struggling
to find a way to excluded these files and have the attachments removed.
Is there a good way to deal with these kinds of tricks in e-mails with
attachments, or a template filter config I can borrow from?
Thank you in advance,
