If the 'greeting name' (HELO/EHLO) does not resolve to the IP address used by the sending server, then the mail is not accepted.
That's ummm, kind of random. There's no reason to expect this.
Someone who does not want to receive mail from legitimate senders can just switch off his MTA ;-)
Legitimate senders should not use fake, false, misleading credentials.
There is no requirement for the greeting name to match any IP, and isn't likely to work for multi-homed and/or clustered machines.
