Decline to service requests by default. Let anyone send through the server
if they are sending to a valid_mailbox_or_forwarding_alias at yourserver. Let
anyone send through the server if they are from a trusted IP**.
* - or if they are sending to a domain for which you provide secondary MX;
at least that's how you configger exim, I assume sendmail is similar.
** - usually machines on the local subnet and a few known-good addresses
