I did not understand what the advantage of use dovecot LMTP with director too.
in "very short" words... with nfs ,the director should avoid concurrent events which may happen with lmtp too, depending to multiple server setup
using director was considered in risk assessment as its another point of failure, and weighed against its claimed benefit, the decision was made its not justified.
mail_location = maildir:/mail/%1n/%1.1n/%2.1n/%n/Maildir:INDEX=MEMORY
With maildir you won't have data-loss without the director, since the index files are auto-regenerated without any problem.
disagree, if we'd had data loss we would have a case to use director, we also had none when we were using qmail and vpopmail, if dovecot did, and as said we are yet to see it, but if it did have data loss, than thats dovecots design issue, but I have no doubt it is that much of an issue.
and from memory the only difference is some messages that just arrive may or may not appear immediately, this is only a problem with imap, and of all the users, we have a some total of about 200 that bother with imap, the other 100K plus use pop3
With mdbox on NFS and no director, you will have data-loss sooner or later:
irrelevant, we use Maildir, it is time proved.
