Hi all,

I'm using forwardemail.net service for www.pricedout.org.uk domain, and occasionally when sending emails from this domain I get the following error:

420 Error for support@forwardemail.net of "Link hostname of "pricedout.org.uk" was detected by Cloudflare's Family DNS to contain adult-related content, phishing, and/or malware. Phishing whitelist requests can be filed at https://github.com/spamscanner/spamscanner/issues." If you need help please forward this email to support@forwardemail.net or visit https://forwardemail.net.

AFAIK, the emails usually go through just fine and the misclassifications seems to happen intermittently.

Would it be possible to somehow whitelist this domain?

Many thanks.

Seems like there is a NS lookup issue on pricedout.org.uk:

Though this wouldn't cause that error to occur. Let me check something.

I've emailed my higher-level contact at Cloudflare to investigate this.

In the meanwhile, I suggest setting an A record for your hostname without the www.

e.g. dig pricedout.org.uk a should return the same that dig www.pricedout.org.uk a returns

Also when you visit pricedout.org.uk you should have it redirect to the www, either use www and enforce it when people visit non-www, or the reverse. Don't have both and definitely have both work in terms of redirection to the other.

I heard back from cloudflare. they said your domain was not flagged and is classified as real estate

also they said that one-off edge cases are a possibility:

We have seen some rare instances where the key value store on our edge network that applies the logic has errors on a one-off basis.
