[Dovecot] NUL characters in POP3 conversation cause Outlook to hang

[Matthew Reimer]

We're being bitten an Outlook bug [1,2] that is triggered by a NUL 
character in a message being sent through POP3. I see that dovecot's 
imap implementation converts 0x00 to 0x80, but this conversion is not 
done for POP3. Would it be possible to add an option to do this mapping 
for POP3 as well?
