which is correct behaviour.
To catch mail that is addressed to non-existent recipients, I add the
following to my virtual_alias_maps hash file:
/etc/postfix/virtual
@example.com ADDRESS_TO_SEND_TO
...where ADDRESS_TO_SEND_TO is the e-mail address to catch e-mails addressed to
a non-existent domain.
Non-existent recipient, again. And this is exactly what causes backscatter.
Don't accept mail to non-existent recipients. If you really must accept it
(why?), don't forward it, especially not to gmail.
