When writing a message, the lines should be cut at something between 72 and 78 caracters.
Apparently, this is done when sending the message, since the correction of that bug:
http://trac.roundcube.net/ticket/1484148But it would be nice if the line endings were visible while typing, so as to know the final aspect of the message before sending it.
I don't see any option to check for that, so I guess it is not implemented. It would be even better if one could choose the line length to use.
(I hope I post in the right place. I don't know which roundcube version I'm using: I'm provided this interface by OVH
