I agree with him. False and useless.

There's zero evidence to show that, "Gmail not to be trusted with important email.", as the title suggests. None of it is factual. All of it is presented as-is with only what appears to be a very poor understanding of MTA configuration issues.

The answer has been here all along early in the thread. DKIM & SPF yet the complainant has simply shrugged it off with, "Well that would cause consistent issues." (which is also false.)

If he can not do basic troubleshooting or understand the importance of the SPF/DKIM settings in a modern MTA system, and as a basic starting point, he can not assert that Google can not be trusted with important emails.

So. False, and useless.
