Verizon Whitelist Policy Verizon Online's spam-blocking procedures block certain IP addresses and domains that are identified as or suspected of being sources of spam, viruses, or other threats. "Whitelist" requests may be made to exempt specific addresses or domains from being blocked by these procedures.
Please note that whitelisted status does not guarantee delivery of email. There are a number of reasons why email may not be delivered aside from the spam-blocking procedures that whitelisted status addresses, including issues with the sender's ISP or the recipient's filter settings.
Whitelist requests should be made only if the sender of blocked email receives the following error message:
ERROR 550 Email from your Email Service Provider is currently blocked by Verizon Online's anti-spam system. The email "sender" or Email Service Provider may visit http://www.verizon.net/whitelist and request removal of the block.
If the sender did not receive this error message, whitelist status may not address the issue. The sender should contact his or her ISP. Verizon Online customers may also check their spam filters and Spam Detector folder. For further assistance, please refer to Email troubleshooting in the Verizon Help site.
To protect its customers and its networks, Verizon Online reserves the right to reject whitelist requests and to revoke whitelist status if granted. Verizon Online may deny or revoke whitelist status without notice for any of the following reasons:
