It's pretty easy to stop messages with null characters if you use
Mimedefang, a milter. A built-in function called SuspiciousCharsInBody
tags messages with either nulls or bare CR or LF. We've let this go
but since we're testing a Cyrus server it looked like we should
stop them coming in.

Which means the MTAs have to accept *and strip* them, as forwading is just
an subcase of sending, IMHO.
Now, if the requirements for a spool (MDA) are the same as those for a MTA,
then Cyrus must accept and strip
