Emails are no longer being sent from Wordfence, but alerts are enabled

If you are no longer receiving Wordfence emails from your site, a common reason is that your email server's IP address has been added to a blacklist, and your WordPress site emails won't be received by many other people, including you.

You can look up your site's domain or IP address, to see whether it's on a blacklist on this URL:
http://mxtoolbox.com/blacklists.aspx

Enter your WordPress site's IP address or domain, and if you see it listed on an email black list, contact your hosting provider for further instructions.

If your site is not on a blacklist, you can also use the "Send a test email from this WordPress server to an email address" option at the bottom of the Diagnostics page on the Wordfence Tools menu, to test if a simple message will be delivered. If that test message is not delivered, your host may need to investigate the issue.
