server version 7.01_GA (open source edition)
desktop version 7.01
some users end up having a read receipt request attached to every email and are unable to send email without the request. Other users are able to send an email with or without a read receipt request. I don't see a setting for this in the desktop preferences or in the server admin console. Is there a way to rectify the situation so that emails from all users typically will not have a read receipt? This has become very frustrating to some of our users and I'm sure fairly annoying to some of our clients.
