Maybe, but those are unusually high maildir numbers IMO. I have approx 8Gb of email messages, but only have a handful of maildirs - this is primarily why I prefer mu4e and org as a powerful mail workflow.
I use to use the old model of sorting email into many different folders, but it was just too time consuming. My inbox was always large and I spent hours each week just sorting and refiling my messages. Now I just have a couple of maildirs for each account - inbox, archived, sent, draft and thats it. For messages I need to track, I create an org-todo with a mu4e link and if I need to find an old message, mu search works fine. Now my inbox has approx 20 messages and I spend no time sorting and refiling messages. Mutt is OK, but does not integrate well with emacs. I live in emacs, so I want my mail reader there as well.
