@neil Google, and Microsoft, I presume.
They're a pain in the arse for the PHP project as well, because they're equating our mailing lists with bulk marketing emails.
@neil @derickr Google and Microsoft are simply bad email providers. Their job is to deliver emails to users, and they fail at that.
The more fundamental problem is that too many users don't seem to understand that it's a choice. If your email provider is bad (and Google and Microsoft are *really* bad) then you should move elsewhere.
About the service that neil said is failing: it's not your service that is failing, it's Google and Microsoft that are failing. People should stop using them.
The choice is being able to email people everywhere except gmail, hotmail, and outlook.com, orrr they get to be your email provider. Not much of a choice, really.
