SMTP Authentication Block list/Brute-force Block list

To help prevent brute force attacks, Spam Experts has added a delay between failed login attempts.

If users have an incorrect server configuration, they may be locked out of their account and unable to log back in again. If this happens, the server's IP address is added to Outgoing > SMTP Authentication Block list.

To allow access again, you can remove the IP from here by clicking the downward arrow to the left of the User column then clicking Remove.

We only recommend removing the IP after they have fixed their authentication issue, or risk being blocked again.

IP addresses cannot be added here manually.
