Like the lady of yore, the "N" flag that indicates whether there is new mail in a given mailbox oftentimes vanishes.
I run "fetchmail" (bound to Shift+g in my setup) and as expected, I now have some "N" flags in the "mailbox index/list" view of mutt.. telling me that some 3-4 mailboxes contain new mail ready for my perusal. After processing the first mailbox (read/delete) I switch back to the mailbox list and... there are no "N" flags any more there to be seen. All the "N" flags that I was seeing _before_ have now disappeared. As a result I have to access each and everyone of my 30+ mailboxes in succession to make sure that I am not missing anything useful hoping that I don't miss one. Has anyone been a witness to this? Happy Friday 13th, and thank you for reading the above...! CJ
