This does not answer the question of how to stop spammers from using
network resources. So that is probably very wishfull thinking but if
another avenue could be taken away from them... Spam is sent to
domain.tld WITHOUT checking MX records.
If you don't include the domain in local-host-names sendmail
should reject everything at the RCPT TO step before DATA
is permitted. That still consumes some resources but should
be insignificant compared to the ones you accept and scan.
or, going with the topic of this list, if you wanted to accept mail for
postmaster and abuse, you could keep the domain in local-host-names,
but filter out any recipients for that domain (except postmaster and
abuse) during filter_recipient.
