[ANN] filter for text-only base64-encoded msgs [LINUX][FOSS]

[Dario Niedermann]

Sometimes you'll get an email - without attachments, just text - and
that email is base64-encoded for no good reason. Spammers have been
known to do that in order to bypass spam filters. Mailing list soft-
ware has been unwisely configured to send out encoded messages. Or
clueless users tweaked their client the wrong way...

The end results:

1. any rule in your mail processing chain matching on message body
will fail;

2. ungreppable messages end up in your stored email.
