"Invalid recipient" should be a 5xx error, or do you expect that these
addresses will be created within the next few days?
(now a message in the outbound queue which will never go)
but that's off topic)
If "invalid recipient" is a 5xx error, the sender will omit the already
rejected recipients on the next delivery attempt. Eventually all invalid
recipients will be removed and - if any valid recipients are left - the
message will be delivered. (And frankly, anybody who sends a message to
tens of non-existent addresses deserves a bit of pain)
