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
2. ungreppable messages end up in your stored email.
