I posted something about that one month ago today.  I made the same
modification to my mimedefang-filter.  Never really thought about it after
that, after all the "fault" is of the sender and/or the sender's mail
software, the filter change is no problem...  I just changed my
mimedefang.pl (from v2.6) for the helluvitt.  patch is attached.  I'm
running it, but I haven't had any senders that were <> yet, so I don't
know if it works or not ;-)  Use at your own risk!!  [ maybe wait, make
sure David doesn't reply saying it breaks something <g> ]
