Hello,
Before I had my ISP setup my IP address's PTR record to resolve to one of my domains, my IP address resolved to '123-243-137-139.static.tpgi.com.au'. If I had used '[123.243.137.139]' as the host name of my mail server, would a Postfix-based e-mail server enforcing 'reject_non_fqdn_helo_hostname' accept my mail, or would the PTR record have to resolve to '123.243.137.139' exactly (not '123-243-137-138.static.tpgi.com.au')?
There is allot I don't know about DNS. Does anyone know if a PTR record can be set to resolve to an IP address?
- Thanks Regards, Nikolas Kallis
