Blacklisted Telus IP address
 

Hello
I am having email bounce back from diveshopscuba.com and when I checked with the web site host, Shaw Business, they were able to determine that my IP address is being Blacklisted by all Hostopia Providers. I am sending the email thru my business account hosted at Bluehost but home internet is Telus. Also similar results with the telus email. So, how do we fix this?
