*If* NUL is forbidden in the RFCs as someone has suggested, then Cyrus is 
doing the right thing by being more 'strict' and making sure that it 
conforms ... perseonally, something I don't have a problem with ... but, 
someone else indicated that it wasn't forbidden ...

If it is actually forbidden though, then we should be starting to petition 
the MTA developers, with 'ammo in hand', to fix the MTAs themselves ...
