Address classes:
LOCAL:
# Default value, not mentioned in main.cf:
mydestination = $myhostname, localhost.$mydomain, localhost
So <u...@smtp.example.com> and <u...@localhost> are local addresses,
likely subject to local delivery via alias_maps and home_mailbox.
Also $myorigin has its default value of $myhostname, so mail to just
<user> is also delivered via local(8).
VIRTUAL MAILBOX:
Domains that are keys in the mysql_virtual_mailbox_domains.cf table.
Are any of the above local domains listed?
This mail is handled via virtual(8) and does not use alias_maps or
home_mailbox.
VIRTUAL ALIAS:
Are any domains listed as keys in virtual_alias_maps table? You have
explicitly configured virtual_alias_domains, so this defaults to
$virtual_alias_maps.
Also are any/all users in either of the above classes subject to
virtual alias rewriting.
It sure looks like mailman is used so at least some addresses are
delivered to the local(8) transport, it is not clear whether these
are always rewritten to non-local addresses via aliases, or not.
OTHER:
The transport table could also change the delivery logic for one
or more domains.
Your question cannot be answered based just on the data you have
provided.
The home_mailbox parameter is used when mail would otherwise be delivered
to $mail_spool_directory for a system user via the local(8) delivery agent.
Whether this is in fact used depends on the details of the various tables.
