Dear all
I had problems with emails being stuck in the outbox. Correcting the server name for the relevant email account seemed to fix the problem. Months later - and having tried on K9 to send few if any emails in the time between - the problem reoccurred: emails where stuck in the outbox for weeks and yet, just now, for a reason unknown, they got sent. (This is not good. An email client needs to reliably send emails.)
Here is another (this second one taken after the emails got sent)
