I've been using mutt for a couple years, and something new just started.
Not sure if it's mutt or another program, but I *think* it's mutt. Then
again, I just started noticing it and haven't built mutt since August (I
build from the mercurial sources). I'm currently running
6196:b01d63af6fea.
Anyway, after a day or so of running, mutt stops recognizing when
mailboxes get mail delivered to them. I get no notification and if I
look in the mailbox list, no boxes have an 'N' next to them to indicate
new mail has arrived. If I quit and restart, mutt notices boxes which
have new mail in them again.
My mail is in maildirs that are populated through offlineimap and
getmail. getmail delivers the mail to dovecot, which filters the mail
and actually puts it in the maildirs. Offlineimap delivers the mails
directly.
Like I said, I'm not sure when this started happening, because mutt
works fine for some undetermined but longish amount of time before doing
this. Like a day, or several days. I just noticed this about two weeks
ago, but it could have been going on since August and I haven't noticed
it.
Any ideas what might be going on here?
