74.201.84.163 Zoho mail server on blacklist for past week

Just had email rejected by Network Solutions server:


http://emailadmin.registeredsite.com/

Indicates the site has been blocked since 12/23/15, so my outgoing mail has had delivery problems for a week now.


http://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a74.201.84.155&run=toolpage#

lists 5 other blacklists.


Is this going to be fixed?  Why has it not been fixed yet?
