We are having some mail rejected by remote mail systems which are identifying a Cloudflare IP address as a SPAM host. The IP is a shared IP address, it’s not ours so how do I get Cloudflare to correct this ?
The IP is resolved from a link in the e-mail to one of our domains, we use Cloudflare for dns and cache.
The error is:
550 5.7.350 Remote server returned message detected as spam -> 521 A URL () in the email resolved to a blacklisted IP: 521 The IP 220.127.116.11 is Blacklisted by cabuseat. Your email looks like potential SPAM and has now been quarantined. If your email is urgent then you should contact the recipient by some other means. locked
Listing at abuseat says:
The infected host name is " www dot phxresidential dot com "
I can’t contact the site - Cloudflare need to look at this please.
