You'd probably need to edit Cyrus source code and recompile.

BTW, Symantec server based anti-virus products will bounce all messages 
with NUL character (and it isn't something that can be turned off 
either).  Some mail servers will do the same.  It isn't Cyrus specific 
thing.  NUL characters are bad in email, and can couse unpredictable 
behaviour in some mail clients, if they don't have code to handle this 
special case (most don't, and fact that things work is more due to blind 
luck, than design).  My advice would be to protect your technically 
unsavvy and unsuspecting users by bouncing messages that contain NUL 
character.
