Does no one else ever delete mail messges? :-)
I use the following in my .muttrc: # Folder hooks folder-hook =Junk 'push <delete-pattern>~r>14d<enter>' This sets to delete mails older than 14 days from my Junk folder any time I open that folder. This way it allows me to scan all the mails for possible falls positives without having to worry mail gets lost if I haven't checked it for more than x days.
