- Domain example.com and its IP address are blacklisted that can be checked on the following site: https://mxtoolbox.com/blacklists.aspx
Domain is blacklisted, possibly, due to spam activity.
As a temporary workaround, it is possible to contact system administrator of the remote server (that hosts email receiver domain) to add the affected domain to a whitelist.
Note: It is possible to involve Plesk Professional Service to handle this task on your behalf, refer to the following page for detailed information:
