What if Citi starts using mail services from another provider with a different ptr. Do you expect them to announce that on this mailing list ? Conversely what if City stops services from one and then a phisher/spammer buys of the server space. Thanks to the stupid whitelist I will be sending all these spams whitelisted until we have angry calls on the customer support helpdesk. This is useless for me to keep tracking what servers Citi ,Bank of America, or ICICIBank uses. I put just 1 line in my ".cf" file and forget about it. Because their SPF record already keeps track. Even the largest banks today are outsourcing their email. FcRDNS works only if the organization runs their own mailing and dont keep changing their mailhost names. Thanks Ram
