I posted a whitelist_from_rcvd usage issue the other day and someone quickly opened my eyes to notice the message didn't have a from address, the log showed 'from=<>'. These people are asking that I whitelist their mail servers. I understand whitelist_from_rcvd uses two parameters, the first being the from address. Is there a way to whitelist the mail server found in the headers alone? Or should I stand to my last response to them, 'use a from address'.
