is "anything" a separate virtual user account?

But only if you created a virtual account called "anything".

Which user should get these mails? If it's not a specially created user
(e.g. postmaster) than it must be user1 oder user2. In this case, do not
use virtual_mailbox_maps but virtual_alias_maps:
In main.cf: virtual_alias_maps = hash:/etc/postfix/virtualaliases
In /etc/postfix/virtualaliases:
@virtual.domain1.com user1.virtual.domain1.com
And don't forget to build the databases with the postmap command.

That's because virtual_mailbox_maps is not for aliases, only for
(non-system) mailbox-users.
