As noted above, that expectation is met only under the conditions
described in the Postfix aliases(5) file. Only you have the necessary
information to determine if the conditions are met.
Note that's aliases(5) as configured with alias_maps (bare usernames
looked up by the local(8) delivery agent), not virtual(5) as configred
with virtual_alias_maps (full email addresses looked up by the
cleanup(8) server).

You are talking about virtual_alias_maps. I have no experience with
running a distribution list with virtual_alias_maps. My experience
is limited to using a mailing list manager and/or aliases configured
with alias_maps.
