ifile and BASE64 mails

I just got my e-mail system hooked up with ifile
and it otherwise works OK, but misses all BASE64
encoded spam (half a dozen or so per day).

I sort my mail to folders with .maildelivery
rest goes to ifile (via ifilter.mh) for processing. 
I read stuff over IMAP with Evolution/Pine/etc.

Any hints? I could start tweaking ifilter.mh
to decode the e-mails before passing to ifile,
but I hope someone has already solved this?
