I have an email that I'm trying to whitelist using whitelist_from_rcvd
and it's not working as I expect. I've created an entry:

whitelist_from_rcvd u...@lanyon.com savvis.net

Here is the corresponding received header:

X-Envelope-From: <u...@lanyon.com>
Received: from S253906HZ1EW06.usstls6-hosting.savvis.net (unknown
[209.16.192.170])

Is it because there is no reverse DNS entry?


Yes.

Notice also that the rule checks the header From:, not the envelope,
and they could be different.
