Hi,

I also have the same problem here, with many clients that somehow got 
into their fu.... Outlook addresses with single quotes for example 
'[EMAIL PROTECTED]'
I have checked and Thunderbird also fails to notify of bad address 
format, so M$ is not the only one to blaim.
Maybe checking this would not be to bad.

P.S.: I would wait for this "future" a bit longer if IMAP should come 
first ;)
