🚨 BREAKING: The "30-Day" Warning (SMTP Auth)

The News: Microsoft has confirmed that the final phase of disabling Basic Auth for Client Submission (SMTP AUTH) begins on March 1, 2026.

The Angle for Digg: "The Final Snooze Button is Gone."

The Detail: Starting March 1st, Microsoft begins randomly rejecting a percentage of SMTP Basic Auth connections. By April 30, 2026, it will be 100% blocked.

Why it matters: Thousands of legacy scanners, printers, and "forgotten" scripts that send automated emails will stop working next month if they haven't been switched to OAuth or High Volume Email (HVE).
