NO FREAKING KIDDING.

I’m running into this with clients for whom we do web site work. Mail not being delivered to Gmail accounts. No 
bounceback, not being delayed, not marked as spam, just black-holed for no discernible reason. Like, clients losing 
money because sales leads never make it to them.

Extremely frustrating.
