As a fairly new Mutt user I have been feeling my way as regards configuration but today I got overconfident.
Exploring ways of filtering out unwanted threads I came across scoring. Set up scores for various subjects and set score_threshold_delete to 100 Restarted mutt, read mail, changed folder, hit [enter] twice and lost all mail from my inbox. Ass/u/med scoring was Spamass like and higher score = worse. Note to self:- Must read TFM more thoroughly and not skip important bits. No loss (apart from time and face) as all backed up but a timely reminder to check what's going to happen when you hit {ENTER] Regards, John -- War is God's way of teaching Americans geography Ambrose Bierce (1842 - 1914)
