On the NULL issue, IMAP does not allow bare NULLs in any data that either 
the server or client sends. If you check the formal syntax you will see 
that the 'literal' element used to send the message content in an APPEND 
explicitly excludes NULL as a valid character. So if Eudora is sending bare 
NULLs that is a protocol bug you can bounce back to them and justify having 
them fix.

NB There is an IMAP BINARY extension in the works that does allow bare 
NULLs, but only when used with the specific extension syntax.

Bare CR or LF is another issue...
