If your DNS is local you won't see that much time savings by using the IMail DNS cache. But in a speed comparison of a memory read vs. a network IO operation the memory read wins.
sure, but we're talking about gaining a few ms in an SMTP session that last maybe 10,000 ms, plus the Imail complexity/work of managing its own DNS cache.
What does the Imail DNS cache use for TTL? it does negative and positive answer caching?
