Why does some email I send get bounced back with the error message 553?

Last Updated: November 17, 2006 12:13 PM

The reason the email was blocked may vary. To learn about why it was blocked and to resolve the problem, you can click the link on the error message (look for the line that has the number 553 in it) and follow the instructions.

An example of the line that has the error message is:

553 Dynamic pool 000.0.0.2.
http://unblock.secureserver.net/?ip=000.0.0.*

The first line explains the error, and the second line contains a hyperlink to a page that explains why you received the message and how to fix it.
