It needs to be just your domains, not *every domain*, because otherwise
you won't be able to deliver bounces, or other outbound email.

That's a bad idea.

That's a bad idea.

You can map wildcard local parts at specific domains to your catchall
mailbox, and even that's generally a bad idea, but less bad than
capturing every domain.
virtual:
@example.com catchall@localhost
@example.net catchall@localhost
@example.org catchall@localhost
vdomains:
example.com
example.net
example.org
main.cf:
append_dot_mydomain = yes
indexed = ${default_database_type}:${config_directory}/
mydestination = localhost.$mydomain
virtual_alias_domains = ${config_directory}/vdomains
virtual_alias_maps = ${indexed}virtual
