Since some time I notice that there is a bunch of 'unread' mails in the send folder, although those mails have been send from the same machine, using the SMTP server of the mail provider. These mails have to be ticked one by one and CRTL-R to mark them read - just opening is not sufficient! (No need to mention that this is somewhat annoying!) Can we do something about this?
