Did notice any warnings from Postfix with "do not list domain XXX

With ":" lookup results in a transport map before the randmap.
The transport map must return ":" for the recipient domain AFTER
canonical and virtual alias mapping. As documented, canonical and
virtual alias mapping happen before transport map lookup.
Have you verified that the recipient domain after canonical and
virtual alias mapping matches the transport map? Does the lookup
return ":"? Postfix logs the recipient domain as "to-<xxx>".
