Hmm... previously I had this in the amavisd-new conf file:

@keep_decoded_original_maps = (new_RE(
   qr'^MAIL$', # retain full original message
   qr'^MAIL-UNDECIPHERABLE$',
   qr'^(ASCII(?! cpio)|text|uuencoded|xxencoded|binhex)'i,
# qr'^Zip archive data',     # don't trust Archive::Zip
));

It's my understanding that the above was necessary in order to take 
advantage of the SaneSecurity sigs. Well, after the earlier hangs, I 
changed it back to this:

@keep_decoded_original_maps = (new_RE(
# qr'^MAIL$', # retain full original message
   qr'^MAIL-UNDECIPHERABLE$',
   qr'^(ASCII(?! cpio)|text|uuencoded|xxencoded|binhex)'i,
# qr'^Zip archive data',     # don't trust Archive::Zip
));

and man the load on clamd has dropped enormously. I saw the remark about 
having the '^MAIL$' line uncommented would be slower, but the difference 
is so wildly extreme. Even when the traffic was rather low, before clamd 
was always at the top in terms of cpu utilization. Now it's barely 
taking any cpu time at all. Naturally the time of day is a factor, but 
we'll see for sure tomorrow.
