If it’s not obvious, that means I have 123k unread emails and 24k read ones. I archive off read emails older than 60 days, but still, that’s pretty pointless and stupid. It’s time to have a purge and unsubscribe from all those lists which I always think I’ll get around to reading at some point.

Update: Just over a week later and with some ruthless pruning, things look much better:

$ find /home/andy/Maildir -type f -wholename '*/new/*' | wc -l
2234
$ find /home/andy/Maildir -type f -wholename '*/cur/*' | wc -l
