Verizon IP address blacklisted
30310016
Newbie

I have a problem sending email through Fios Internet.
It is NOT about email account with Verizon or AOL but our own domain mail sending via Fios.

Some of our mail are rejected by recipients due to MTA’s poor reputation. We checked our sending IP address and found that the address, 173.68.xxx.xxx (can I wrhite it here? I'm not sure), is 'blacklisted'. This address belongs to Verizon, not our domail server. How can you solve the problem?
