There is a hard limit of around 64k files/directories per directory, but I believe there is a performance hit long before that. I should not be hard to put the Maildirs in subdirectories, since you can just set mailMessageStore in LDAP. I use 'letterhomes' /mail/u/user/Maildir, /mail/a/andreas/Maildir, etc. There was discussion on this list about a month ago about using hashes for the subdirectory names, for more 'balance' between the subdirectories, but I am not sure how much that will help, especially if you are not really close to pushing the directory limits.
