A small heads up, some forum notification messages may be slowed to Yahoo and Hotmail/Outlook. The IP assigned to the forum mailer is being throttled on the receiving side due to abuse by another customer of my provider. I've sent a support ticket and presume the issue will be resolved within a few days (if not by Wednesday), but I don't want anybody to be confused or think this is normal if a notification takes the scenic route to arrive.
This should be resolved. My provider switched the IP address for the mailer and the logs are now showing proper delivery speed.
