Since: Dev Builds Only

The functionality described in this section requires a dev build of KumoMTA. You can obtain a dev build by following the instructions in the Installation section.

local mail_auth = require 'policy-extras.mail_auth'
local auth_result = mail_auth.iprev(IP)

The mail_auth.iprev function performs the iprev authentication method as specified by RFC8601 Section 3, and returns an AuthenticationResult representing the status of the check.

The IP parameter is a string representation of the IP address; for example, "127.0.0.1" for an IPv4 address of "::1" for an IPv6 address.

See mail_auth.iprev_msg for a version of this check at accepts a Message object instead.
