I did some checking. The list server (ilug-bom.org.in has no MX records, so mails are delivered to the A record which is 74.207.228.67) requires all of the following resolving properly for it to accept emails:
1. The connection must be from an IP address that resolves in the reverse direction. 2. The reverse-resolved name in (1) must forward-resolve too. 3. The name used in the HELO/EHLO needs to resolve as well. 4. And finally, the domain of the address in the MAIL FROM should resolve too. Best would be to relay through Gmail.
