If you'd like to adjust your Greylisting settings, reach out to VCGSupport@VCGCorporate.com and we can disable or re-enable it for you.
Greylisting is used to prevent bulk emailers and SPAM bots from getting their email delivered. Greylisting is a temporary rejection of the message that forces the sending agent to resend the message at a later time. Legitimate senders will attempt a retry the message later while bots and spammers normally will not.
Greylisting is turned on by default on shared mail servers in our ongoing battle against spam. We recommend that you DO NOT disable greylisting.
