We are running Dovecot 1.0.0 using mbox format (currently in the midst of conversion from UW IMAP). We discovered today that the Dovecot LDA is accessing the user's INBOX at delivery time! Not only do our users
If you're willing to pass on delivery-time indexing, and you assign one unix uid per account, then you can instead consider using other delivery agents - and just use dovecot to serve.
I use procmail on my system; and on some mailboxes, I use deliver; some I deliver direct via procmail to reduce deliver times to accomodate the flow rates that hit those specific mailboxes (alerts in a very large production environment that are still smtp based).
