What might cause an email to bounce back if you know you have the email address correct?

When a user attempts to send an e-mail, he is telling his e-mail system to look for the domain of the recipient (for example, webopedia.com) and the domain's mail server. Once the e-mail system makes contact with the recipient's mail server, the mail server looks at the message to determine if it will let the message pass through the server. If the recipient's server has predetermined that it is not accepting e-mails from the sender's address (for example, if it has blocked the address for anti-spamming purposes), the server will reject the message and it will subsequently bounce back to the sender. The message will also bounce back to the server if the mail server on the recipient's end is busy and cannot handle the request at that time. When an e-mail is returned to the sender without being accepted by the recipient's mail server, this is called a hard bounce.
