Looking to see how other MTAs behave:
sendmail accepts and passes NULL
exchange seems to actively delete NULLs from message bodies
NIMS Sending a NULL to Novell NIMS causes the SMTP session to
hang in DATA phase till timeout !!
FWIW, I've queried this with the NIMS developers, and they say their code
can't cope with NULLs as its expecting this to be end of string marker.
Furthermore, they claim this gives them a performance advantage over the
other products listed above, since they can operate in block mode rather
than character mode. ( I'm unconvinced )
Meanwhile back at the coalface, remote sites sometimes send us mail with
NULLs, and apart from asking them not to, there's not much we can do...

Sounds like that would help. In this case I'm not trying to match the
NULLs - just want to match a pattern elsewhere in the message.
