Given all the hardware abstraction layers. I forgot to mention that on a clean start of dovecot (after making those changes), I counted 25 msgs delivered to this single mailbox (all INBOX) in a second. Then it slowed down. Maybe the answer is less LMTP connections and increase the number of messages per connection. I have Postfix configured to do outbound connection caching and I've seen entries in the logs indicating 30 messages on a given connection. I'll have to look into how to limit dovecot to a certain number of LMTP processes. -Chad
