QQ Mail (smtp.qq.com and smtp.exmail.qq.com) is known to cause duplicate email issues with Discourse. The SMTP server does not return proper acknowledgments, causing Discourse to retry sends that already succeeded. This adds a ProblemCheck that displays a warning on the admin dashboard when QQ Mail SMTP is detected, linking to recommended alternatives.
