Maybe *ideally* it needs to be fixed by the MTA. However, just casually 
following this list and the postfix-users list, whenever the issue of 
NUL characters have come up, it has always been centered around Cyrus. I 
know that there are folks using Postfix with other IMAP servers, and 
never once have I noticed this topic in relation to these systems. As 
best as I can recall, it has always been in relation to Cyrus.

So, my take on this is that while it may be *ideally* better dealt with 
by the MTA, perhaps *practically* it is more productive to remedy the 
software that is bitching the most about it. It certainly would cut down 
on the frequency that this issue comes up on this list....
