Thanks for the great work and the informative write-up. table-procexec looks really promising. Packages like the Go and Python examples will make using this functionality a breeze. I am really looking forward to see this in a production ready state.

New install, finally got working basic config but it looks different than all the guides.
smtpd.conf:
...
table credentials passwd:/usr/local/etc/mail/passwd
listen on lo0
listen on em0 port smtp filter { check_dyndns, check_rdns, check_fcrdns, senderscore, rspamd }
listen on em0 port smtps tls-require pki "mail" filter { check_dyndns, check_rdns, check_fcrdns, senderscore, rspamd }
listen on em0 port submission tls-require pki "mail" received-auth auth
action "local_mail" mbox alias
action "virtual_mail" lmtp "/var/run/dovecot/lmtp" rcpt-to virtual
action "outbound" relay
match from any mail-from for any reject
match from local for local action "local_mail"
match from any for domain action "virtual_mail"
match from local for any action "outbound"
match from any auth for any action "outbound"

Dovecot:
passdb {
args = /usr/local/etc/mail/passwd
driver = passwd-file
}
disable_plaintext_auth=yes
ssl = yes
ssl_cert=/usr/local/etc/mail/full.pem
ssl_key=/usr/local/etc/mail/key.pem
