This is the sequence (ie a blank line) which indicates the end of the header section, so this would explain precisely the behavious that is being seen.
What alternative behaviour would be correct? I suspect that it would be better to remove \r instead of adding an extra \n as currently happens. An alternative would be to reject malformed messages instead of attepting to fix the message and getting it wrong. Anyone know of a good reason why cyrus converts bare \r to \r\n?
