Latest Message<\/th>\nTitle: Users’ legitimate inbound email messages are being incorrectly marked as phish<\/p>\n

User impact: Some users’ legitimate inbound email messages with URLs are being incorrectly marked as phish by anti-spam detection.<\/p>\n

More info: We cannot provide the list of affected URLs in detail.<\/p>\n

Current status: We’ve addressed some issues that were delaying the script and have confirmed that 50 percent of all affected email messages have been released from quarantine. We’re continuing to monitor the script as it progresses towards completion.<\/p>\n

Scope of impact: Impact is specific to some users who are expecting to receive inbound email messages and are served through the affected infrastructure.<\/p>\n

Start time: Tuesday, October 29, 2024, at 5:39 PM UTC<\/p>\n

Root cause: A recent rule set change in our automated anti-spam procedure is incorrectly blocking email messages containing certain types of URLs. This change is causing inbound email messages to be marked as phishing and quarantined because some signatures are being flagged as malicious.<\/p>\n
