The big reason not to use IMAP is that it's not efficient for 5K+ concurrently connected clients. I believe Dovecot implements a local delivery agent, so presumably postfix contacts it via LMTP? I'm hoping LMTP doesn't mandate a distinct TCP connection to a server for each message, vs. streaming messages over a single connection, otherwise the number of concurrent connections would exceed what's practical.
