Virtual Aliases. A virtual alias `"info@example.com" = "user1@example.com"` means that
all mail to `info@example.com` is forwarded to `user1@example.com`. Note
that it is expected that `postmaster@example.com` and `abuse@example.com` is
forwarded to some valid email address. (Alternatively you can create login
accounts for `postmaster` and (or) `abuse`). Furthermore, it also allows
the user `user1@example.com` to send emails as `info@example2.com`.
the user `user1@example.com` to send emails as `info@example.com`.
It's also possible to create an alias for multiple accounts. In this
example all mails for `multi@example.com` will be forwarded to both
`user1@example.com` and `user2@example.com`.
