I had OpenARC configured for a while.

I ended up commenting it out as I found effectively no value in it. I
came to this conclusion because it's so minimally deployed and the
places that have deployed it don't have a way to learn who to trust or
not trust.

I'd love for the situation to change. But I'm not holding my breath for
it to do so.

I don't recall doing anything special to get it to work. It is
exceedingly similar to DKIM as far as installation and configuration goes.

I do. With OpenDKIM and OpenDMARC as well. Call me lazy, but I'm reusing users/groups.

sendmail.mc:

INPUT_MAIL_FILTER(`openarc', `S=inet:8893@localhost,F=T,T=R:2m')

openarc.conf:

AuthservID domain.com
AutoRestart yes
BaseDirectory /var/run/opendkim
Canonicalization relaxed/relaxed
Domain domain.com
KeepTemporaryFiles no
KeyFile /etc/opendkim/keys/default.private
Mode sv
PidFile /var/run/openarc.pid
Selector default
SignHeaders to,subject,message-id,date,from,mime-version,dkim-signature,arc-authentication-results
SignatureAlgorithm rsa-sha256
Socket inet:8893@localhost
SoftwareHeader no
Syslog Yes
UserID opendkim:opendkim

I'm a Lisp variable -- bind me!
