Hi, Pondering MTA-STS validation.
My understanding is the recommendation is to use DANE as the default (smtp_tls_security_level=dane), but if you want MTA-STS for select domains you can point them at a transport that requires X.509 validation. Realistically, Gmail and Yahoo do not care about my MTA-STS reports. All they care about is that I validate their X.509 certs. Is there any reason to use something like mta-sts-daemon in that transport instead of just setting smtp_tls_security_level=verify ? Thanks, ==ml -- Michael W.
