Hi,

I am unable to send emails to friends and clients with .ns.sympatico.ca or sympatico.ca or bell.ca email addresses from my domain (lovethewayyoutravel.com) which has been verified and is working for all other providers. How do I go about getting this block removed by Bell? 

The error says Message Blocked. The response from the remote server was: 521 Service unavailable

Thanks,

The IP address associated with lovethewayyoutravel.com is blacklisted in 1 database.

That is likely your issue.

Interesting. Thanks for the insight. Sadly the site that has supposedly blacklisted my domain seems to not be reputable itself, so getting that corrected is going to be a problem.
