I would recommend using this if they hit SPF_PASS or DKIM_VALID_AU whitelist_auth *@*.comixology.com If they don't have good SPF or DKIM like this one, then use: whitelist_from_rcvd *@*.comixology.com amazonses.com The "amazonses.com" would be the part of the sending mail server's name when it has good FCrDNS. If that mail server doesn't have good FCrDNS, then use: whitelist_from_rcvd *@*.comixology.com [ip.ad.dr.ess] whitelist_from should be the last option and I only use it on a full email address that is very unique so spammers won't be able to match that by accident from any source server or IP address. -- David Jones
