My question is how to know my public ip address was blocked by Spamhaus Blocklist?
if it was blocked How can I remove my public ip address from Spamhaus Blocklist?

Thank you,

HI

I can sent to yahoo.com and gmail.com, but I still cannot sent to all domain such as bokortechnology.com, outlook.com and other, and when I sent it show the error below:

Failed to connect to SMTP host BOKORTECHNOLOGY.COM because SMTP Protocol Returned a Permanent Error.
What wrong with it? I need your help.

Thank you.
