  Please be sure to scrub any real information, like email addresses and domain names from your post before posting to a public forum. Also, wrapping that data in code tags makes it easier to read.

  Your first post contains no real details, the second post is google telling you that you're forwarding too many emails and are being rate limited, I believe. When a cPanel user that prefers gmail over your email offerings, and sets up a forwarder on his account so that all email to johndoe @ domain.com (hosted with you) is forwarded to his gmail account, ALL MAIL sent to johndoe is forwarded, that includes all spam. None of it is scanned by your system, its all just forwarded. If that user has his email address posted publicly anywhere, he's forwarding lots and lots of email (more spam than email, probably) to gmail. Bad idea. You would do yourself good to read those links provided in the rate limiting message a bit closer. 15] Our system has detected an unusual rate of 421-4.7.0 unsolicited mail originating from your IP address. To protect our 421-4.7.0 users from spam, mail sent from your IP address has been temporarily 421-4.7.0 rate limited.

  I have fixed the issue by clearing the exim DB and reset the domain from /var/cpanel/email_send_limits/track/domainName and /var/cpanel/email_send_limits/cache/domainName

  Hello :) I'm not sure those changes would make Google accept your email. It's likely the the temporary block imposed by Google was lifted after a period of time. Thank you.
