What is the recommended setup for mbsync > with local maildir usage? Is speed still an issue? Hi Erik, speed can be an issue with nnmaildir. It depends on what mbsync does to file update times in the various maildir directories. I switched to nnml for my local email storage as it's a lot more efficient. For nnmaildir, my groups had to be rescanned every time and this operation takes O(n^4) time, where n is the number of emails in the group. The rescanning was necessary, in my case, because I was using unison to keep 3-4 systems in sync which meant that gnus had to regenerate the index tables it uses for each group. But if mbsync is smart, you may not encounter this issue. Try it and see? eric -- Eric S Fraga with org 9.5.2 in Emacs 29.0.50 on Debian 11.3
