This was not stated in the OP.
in effect, yes, I was sending to the removed user on another server. I have sent to the “moved” user from an outside address and it works as expected. I believe the issue is that when I send a test email, the moved user was on the same server and therefore considered local. Somehow, postfix still thinks the user is on the old server even though I have removed all references to it that I am aware of.
It sounds like you are trying to share one domain's hosting among two or more servers. This is not a trivial thing to do. One way to do it is with per-address transport_maps, routing each address to the correct server. You are not doing this. Another way to do it is with Dovecot director, and likewise, I see no evidence of this. If, as it appears (STILL without logs and complete config as per DEBUG_README.htkl#mail), you have simply assigned each server the authority of the domain in virtual_mailbox_domains, users on one server will not be able to contact users on the other one[s]. And mail from outside will be playing Russian roulette: delivered if the correct server is reached, rejected otherwise. How big is this operation? How many thousands of users, how many domains? If as I suspect, you're not that big, YDIW. Just go with a single server and make your life easier. -- http://rob0.nodns4.us/
