550 delivery failure

I am a new user. I setup the service and it working both in and out.

However, I use a website which utilizes a Contact Us page, sending mail via a php script. The failure, from my mxroute account, was:

SMTP error from remote mail server after end of data:
550 High scoring spam message has been dropped, likely blacklist

The DMARC record looks like:

v=DMARC1; p=quarantine; rua=mailto:xx@yy.com; ruf=mailto::xx@yy.com; fo=1;"

Is there a way to whitelist inbound addresses?

On a high level without looking into this specific case, I’ll want to let you know that if you’re sending email from your server to ours, it means you’re running your own mail server on that server. If that is the case, you’ll need to do all of the things that a mail server admin needs to do in order to set up a proper functioning mail server. You need valid reverse DNS, a matching A record (forward confirmed reverse DNS), you’ll need to make sure the emails are sent from a valid address and all that jazz.

Alternatively, you could have your website authenticate via our SMTP and send through us to yourselves. Why re-invent the wheel when we’re already running a mail server for you :slight_smile:
