Postfix: how to explicitly permit "joeblow@mydomain" from certain address ranges
One of our clients uses a mobile client, which "helo"s with a non-resolvable hostname (which contains the correct IPv4 address in the name but does not resolve). I'd like to be able to config PERMIT "joeblow@mydomain" when the helo-name is "*.mobilepool.carrier.net". Can anybody give me a hint how to do this, if it is even possible?
Right now it just rejects based on not resolving the HELO name.
Thanks
