My incoming mailboxes (as specified to mutt) get periodically backed up and thus the 'accessed' time gets updated and mutt doesn't see them as containing new mail.
However when mutt opens these mailboxes it *does* recognise that they have new mail in them and flags the new mail with an 'N'. Is there any way I can ask mutt to actually scan through all the mailboxes rather than just look at the file times to see if there is new mail in them? -- Chris Green
