Feature Request: rDNS lookup for sent-from IP address

[skeels78]

It would be very useful to see the resolved hostname of each IP address being reported on. If the rDNS name of an IP was displayed under the IP Address for a record, it would make troubleshooting much simply by only having to glance at a record rather than doing manual lookups.

I've been taking on new domains that are experiencing deliverability issues - DMARC-srg has been a crucial tool in finding domain configuration errors. The ability to see the names of specific servers at a glance will help quickly determine whether it should have failed, or passed, depending on the server sending the mail.
