Tarpitting occurs if you establish a large number of email connections to the mail server in a short period of time. The email server temporarily will block the IP address, usually for a period of 10 - 15 minutes.

To avoid tarpitting, simply limit the number of connections that you establish to the email server per one minute period. In our shared hosting environment, tarpitting prevents any single email user from monopolizing server resources so that everyone can enjoy reliable email server performance.

If you have been tarpitted by the email servers there is no need to contact support. Tarpitting will automatically release within 15 minutes.
