graylist or gray list is an existing technology for email servers (SMTP). In order to avoid receiving spam, this technology can be used in conjunction with other lock technologies. It basically consists of making a temporary blockade to receive email for a period of time. After this, a new attempted email delivery is accepted in a short term. If the email is delivered again within this opening period, the server’s internet address and the email domain is added to a release list, being expired only after a long period without use. If a new attempt is not made within this short term, the email is blocked again in future attempt.

It seems like a fundamental technology, but it is based on the fact that servers that make millions of mass messages do not have the ability to be resubmitted in all emails that have temporarily failed.
