Reverse DNS Base "none" #293

Closed morphic09 closed 2 years ago

morphic09 commented 2 years ago

Hello,

we are setting up parsedmarc for the first time. Everything looks good so far except for the reverse DNS lookup. The strange thing is, that we get a "none" for the same IP address which gets resolved for another entry. As you can see in the screenshot the clever reach IP is resolved for some mails and for others it is shown as "none".

Seems to have been a temporary problem with the connection to the dns server.
