smtpd: access.db?

Hi,

I'm in newbie mode again. I'm working on replacing an old OpenBSD server
running Sendmail with a new one running smtpd. With Sendmail, I rely
heavily on the access.db feature to block TLDs, usernames, email
addresses, and domains. Is there an equivalent feature with smtpd?

Also I can't see any reason why spamd shouldn't play well with smtpd,
since it's more a feature of pf.conf than Sendmail. Please yell if I'm
wrong.

Thanks,

Steve
