Two things happened about the same time -- I upgraded mutt on my linux system, and I upgraded my smart phone. The phone matters because I suddenly had enough memory for various apps which had long since been squeezed out of the old phone, including K-9 email.
Ever since, the linux mutt has aperiodically closed the mailbox with a message which disappears too quickly for me to see, and usually happens when I am not looking at email anyway. This happens several times a day. It sometimes, but not even a majority of the time, seems to be vaguely related to having checked email on the phone recently, for various paranoia-induced definitions of 'recently'. There are also times when I check email on the phone and linux mutt soldiers on with no problem. But a few times, I have been curious enough about this relationship to stop looking at email on the phone, and linux mutt seems to not close its mailbox as often. On the other hand, I have always been able to open a new screen session and start a new mutt when the main one is in the middle of composing email, and never had any problems with closing the mailbox. I realize this is all too vague to be very useful. But I wonder if K-9 does anything different that would sufficiently upset linux mutt to confuse it and close the mailbox? The main difference I see is that K-9 sets up some kind of push notification with the server and knows of new email instantly rather than only checking every minute as linux mutt does. Speaking of which, is there any way to get mutt to handle push notices from the mail server? I suspect not, since mutt is a mailbox reader, not an smtp client as such. Linux is Ubuntu 13.04, and its mutt is 1.5.21. Don't know what the mail server is, but it serves up IMAP. -- ... _._. ._ ._. . _._. ._. ___ .__ ._. . .__. ._ .. ._.
