Message rejected because of RBL policy

Every so often we will get reports that emails being sent FROM @yahoo.com accounts will receive a rejection email when sending to our company.

Remote host said: 550 5.7.1 Message rejected because of RBL policy [MAIL_FROM]

I have ran mxtoolbox on our domain/IP and everything checked back clean.

I have also sent a test email from my machine outside of the office network from a yahoo.com account and have not received a bounceback/rejection.

Is this something on our end or the sender's end?

What do you have for Spam filtering in front of your mail infrastructure? It is most likely coming from that and not the sender (Yahoo) You may not get it in testing because your test messages may not meet the requirements that triggered the rejection.

You need to review the configuration of your antispam software - because it is you that is blocking the messages. Looking on MX toolbox etc isn't going to help.

The reason it hasn't happened for all messages is probably because just one of the Yahoo servers (or a small number) are on the blacklist. As they are a major provider that is an occupational hazard.

It is a risk you taken when using Blacklists, you are allowing someone else to control what email you receive.
