I am running a multisite install of WordPress. None of the system messages are getting delivered to gmail. I've tested sending to a non gmail address and it works fine. They don't go to spam - they just don't get there at all.
I installed Configure SMTP based on other posts I found, and it didn't work, even when I changed the from address to be a real, non google address on my servers.
This is affecting all sites as far as I can tell. Can anyone help me figure this out?
