to UW-IMAP ("c-client") to use subdirectories "/var/spool/mail/00/" to "/var/spool/mail/99/" based on a trivially simply "uid mod 100" algorithm. (Our uids are random; our usernames are not.) Thus we had 100 subdirs each of about 200 entires. Efficiency and performance vastly improved, and we've been running like that ever since.
Now we are considering migrating to dovecot...
Does dovecot do file creation/deletion in this (or similar shared) directory? (And so would it be liable to the same inefficiency problems?)
If you are migrating, why not change to maildir in $HOME?
Other local political constraints mean that this proposed UW->dovecot transition has to be a minimally invasive thing. It is viewed as a band-aid onto the existing service rather than as a major upgrade.
(Yes, I'd love to re-work the whole lot, including the folder locations. But that's not an option...)
