Last time I had a problem like this, I piped them all through tr -d '\000'.
Nowadays, postfix is set to reject this crap before it comes near Cyrus in
some places, and in others (where we need the messages), we strip the NULs
away shamelessly.

After all, common courtesy of not modifying data in-transit extends only to
email, and whatever something with embedded NULs is, it certainly ain't
email.  They just resemble email enough that they can (often) be converted
into email with some NUL-stripping ;-)

The same goes to messages with empty message-id headers. We strip them away
so that they become email ;p
