Naturally, I am inclined to allow messages with NUL characters to be delivered, as bouncing legitimate messages to unsuspecting, technically unsavvy senders is not an option.
How can I have Cyrus ignore NUL characters in messages?
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.
