Virtual alias lookups are documented (man 5 virtual).
As a quick read shows, tables such as Berkeley DB or *SQL are
searched with the full address, the address localpart, and the
@domain. There is no mention of parent_domain_matches_subdomains
in the virtual(5) manpage.
To match "all subdomains", you need to implement the table with
regular expressions.
/etc/postfix/main.cf:
virtual_alias_maps =
hash:/etc/postfix/virtual_alias
pcre:/etc/postfix/virtual_alias.pcre
/etc/postfix/virtual_alias:
# One-on-one mappings here.
us...@example.com us...@example.net
/etc/postfix/virtual_alias.pcre:
# Wild-card mappings here.
/^(.*)@([a-z0-9_]+\.)*example\.com$/ $...@example.net
