The critical ones are any ip's that are SMTP clients sending mail to other mail servers. Each sending ip should have matching PTR and A records. Of course, the reverse zone delegation must be done and the delegated NS responding. For all CF or web apps that send mail: 1. the envelope @sender.domain must have A and/or MX records. 2. The MX for @sender.domain must accept mail for [EMAIL PROTECTED] That is, in your CF apps that send mail (and that you want to give the best chance of being delivered), just don't invent any old [EMAIL PROTECTED] You will have no success with MX's that do "sender address verification" or DNS validations of @sender.domain.
