Spammers are clever, no doubt.
On the "gateway", they have to get thru spamd and only mail for legit
accounts is accepted... among many other rules.
The "mailserver" has smtpd_enforce_tls=yes and
smtpd_sasl_auth_enable=yes set, so, spammers would be stopped
there... unless they had an account <grin>.
