White list based on host Received From

[Dean Clapper]

Is there a way to white list based on the IP using the Received from.  We 
have whitelisted our local domain but have noticed some that spoof our 
domain.  However the Received from tag is usually a different IP.

Is it good practice to whitelist using IP?

thanks
Dean

whitelist_from is a bad idea for exactly the reason you found.  Use
whitelist_from_rcvd or whitelist_from_spf instead.
