Need to reject null characters

[Brent Addis]

What do you mean by null characters?

Do you mean <> ?

I wouldn't recommend doing this at the MTA level as it tends to break 
sender callout checks (Assuming you ended up upgrading postfix)

I'm sure your users will get mighty annoyed when they find mail not 
being delivered.

Plus its in the RFC's that you should accept these, and we all follow 
the RFC's, right?

If your not meaning <> as null, forget my posting.

:)
