Thanks. I didn't know that was changed. Thanks!
That was the most plausible explanation, most of the time that yields the right answer. > In my scenario, should I use relay in transport_maps?

If the parenthetical (this) means that the MTA in question is handling content filtering between the inbound MX host and the downstream message stores, so that all mail flow is one direction, then it makes little difference which transport handles all the mail. The smtp/relay transport split is for bi-directional MTAs, where at peak loads you get lower latency for inbound mail when the outbound mail direction is congested. One should also generally use a separate transport for the advanced smtp content_filter than for post-filter delivery, don't want one competing with the other. If you still have a question along these lines, start a new thread, and ask it properly. My reply should not be significantly longer than your question. -- Viktor.
