• Sometimes, an email address is greylisted, meaning that it is blocked by a given mail server from delivering email to it. After a specific amount of time, a day or two, the greylisted status is removed and the delivery of email from the given email address can proceed to the mail server where the greylisting occurred. If the cut-off time for the greylisting period passes and the emails to the given email address are still being bounced back, the email address of the sender, may have been blacklisted or flagged by the spam filtering system of the mail server of the recipient’s email account. To resolve this problem, you will likely need to contact the Help Desk of your email service provider and indicate that you are unable to send email to the given email address after a day or two since the emails began to be bounced back so they can put in a request for the email address of the sender to be removed from the blacklist.
