[dmarc-discuss] Suggested DMARC policy for PEC (Italian certified e-mail)

For now, rather than leaving all sub-domains open, I would recommend
publishing an explicit record for pec.salicetti.it with a p=none and
setting salicetti.it back to sp=reject. This will put the reject policy
back in place for all other potential sub-domains, but the explicit record
for pec.salicetti.it will mean that it will not inherit the sub-domain
policy from salicetti.it
It sounds like deliverability is absolutely critical on these messages so
possibly you wouldn't move forward with a stronger DMARC policy on this
sub-domain. But potentially you could check with the Certified Email
Provider to see if they have options to authenticate the mail.
