there’s no generic firewall, but upas has some filtering options. smtpd(8) reads the file /mail/blocked for blocked addresses, and has the -k flag to block ip addresses manually. the validatesender script (called by upas) checks for a spamhaus file at /mail/lib/spamhaus. there are also ratfs(4) and scanmail(8), which provide more complex filtering mechanisms.
