Update to Real Time Blacklists
To prevent any false positives, three of these RBL’s must be hit to reject the email.
We also use a Bayesian filter that will reject mail with high spam probability scores.
If you are a JNH Solutions client and are having trouble receiving email from someone that has managed to get themselves on a blacklist, please contact us and we can allow them a temporary inclusion until their mail server is removed from all blacklists.
So how do you know if your email server is on a blacklist? Check out MX Toolbox to see if your mail is being blocked.
