Google to customer: Go fuck yourself. In the cloud.

Sounds like he needs to get himself an SPF DNS record (assuming his email is at the linked domain).

Yes, his situation sucks, and it's also bad that seemingly no-one at Google cares (though as was mentioned in the comments there, they do have phone + email support for paying apps customers). It doesn't really sound like Google's fault or problem, because raising whatever limit they have on his account won't fix a problem with someone presumably using his misconfigured domain to send spam, triggering the limit in the first place.

Of course, that doesn't change the fact that Google really doesn't seem to value customer service.

Lame blog post. Totally wrong, and the user didn't go far enough to solve his own problem. px1999's reply about SPF/DKIM setup should be looked at. If that doesn't work, you can contact google and let them know the problem.

"The Cloud" as a robot that can't be interfered with by the operating company is a stupid notion. If that were the case most cloud and SaaS companies would go out of business because they'd never be able to fix problems that come up. Most systems can be looked into, and can be tweaked in numerous ways.
