SMTP server temporarily not available

I am getting 421 status code errors below trying to do an email to text.  Why is this happening?  We have SPF, Reverse DNS, DMARC and DKIM verification in place.

Howdy cblaze22. A lot of times this type of error resolves it's self. So I see this was sent to us last night around 5pm. Are you still having this error?

This has nothing to do with my phone.  This is a SMTP server.

Well why are your mail servers rejecting our emails? We are speaking to your cloudmark servers about this but thought this was a good place to ask also.

Are you sure you have the right company? What email are you trying to send to within Sprint?
