Or am I missing the point of ALPN? At least one use, tangential to that RFC-suggested is protection against malware.

I agree that implementing such checking does not require a formal allocation of an ALPN for mail - but allocating one would not preclude it either. -- Cheers, Jeremy _______________________________________________ ietf-smtp mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf-smtp
