[QUOTE]The response from the remote server was:

• 550 "JunkMail rejected - JunkMail rejected - mail-eopbgr820134.outbound.protection.outlook.com (NAM01-SN1-obe.outbound.protection.outlook.com) [40.107.82.134]:26094 is in an RBL:
• JunkMail rejected - spruce-goose-as.twitter.com [199.59.150.88]:36091 is in an RBL:

Since last night every server appears to be on the RBL and is rejected. I notice that the name of the RBL is missing and suspect that may indicate a misconfiguration or a failure somewhere between the mail server and the RBL. What is the most direct way to trace this path to verify functionality and identity any failures? Screenshots show some config. Honestly, I am not sure how some of these were added and assume they are provided by the system. Thanks! 56305 56309

  UPDATE: dnsbl.njabl.org hacked Through trial and error, I discovered dnsbl.njabl.org to be the source of the dysfunction. Apparently it is returning a false positive on every check. Found this report:

  Hi @summitscout I am glad you found the source of the issue, this isn't the first time one of the RBL's has been subject to this behavior. I want to point out that these are custom added RBL's the only ones we add by default are Zen and SpamCop.
