Status=bounced (host mail.domain.com7[www.xxx.yyy.zzz] said: 550 Sender IP reverse lookup rejected

Howdy, a search did not turn up an accurate issue content so I’m creating a new issue base on: reply email bounces with the claim the host reverse lookup is rejected in spite of what my /admin site displays included below.

The question is: is it me or them?

Please advise.

Thanks in advance.

Hi,

Can you paste the headers of the email you sent and was rejected? Just the headers, not the content.
