Does this hold true for address expansion within
virtual_alias_domains? In other words, if I have
virtual_alias_domains = example.com
and then I set up a virtual alias map
bigal...@example.com -> addre...@external.example.org
-> addre...@external.example.net
[etc]
such that all of the members of bigal...@example.com are external to
postfix, do I still need to define
owner-bigal...@example.com
in order to avoid the potential repeat deliveries in case of
deferrals?
