You could eliminate the intermediate virtual-alias step and list
the mailman domains in "mydestination", and the mailman aliases
file in "alias_maps"
mydestination = $myhostname localhost.$mydomain lists.$mydomain
alias_maps = hash:/var/lib/mailman/data/aliases
But this has the minor drawback that UNIX system accounts can
receive mail as u...@lists.$mydomain.

If I'm not mistake, the mailman aliases file does not specify the
email domain, so the email domain would need to be specified in
some other way.
If Postfix implemented automatic discovery via the file system,
the directory tree could look like this:
Use local(8)-style alias (not username) lookup for lists.example.com:
/etc/postfix/domains/lists.example.com/class -> local
/etc/postfix/domains/lists.example.com/aliases.db
Use virtual alias expansion for another.example.com:
/etc/postfix/domains/another.example.com/class -> virtual_alias
/etc/postfix/domains/another.example.com/aliases.db
/etc/postfix/domains/athird.example.com/class -> virtual_alias
/etc/postfix/domains/athird.example.com/aliases.mysql
Use local(8)-style username and alias lookup for myname.example.com,
example.com and localhost.example.com:
/etc/postfix/domains/myname.example.com/class -> local
/etc/postfix/domains/myname.example.com/users -> passwd
/etc/postfix/domains/myname.example.com/aliases -> aliases.db, aliases.ldap
/etc/postfix/domains/myname.example.com/aliases.db
/etc/postfix/domains/myname.example.com/aliases.ldap
/etc/postfix/domains/localhost.example.com -> myname.example.com
/etc/postfix/domains/example.com -> myname.example.com
Relay mail for the following:
/etc/postfix/domains/one.example.org/class -> relay
/etc/postfix/domains/one.example.org/recipients.db
/etc/postfix/domains/two.example.org/class -> relay
/etc/postfix/domains/two.example.org/recipients.db
I suppose that all this could be hidden under a sufficiently powerful
lookup table API: to find out the address class of localhost.example.com,
search the tree for each address class for the named domain; to
look up an alias for localhost.example.com, discover and search
the aliases.* files under domains/localhost.example.com.
