Need help removing our IP address from the verizon e-mail blacklist
Enthusiast - Level 1

Dear Verizon Online Security staff,

as we did not receive any replies to the e-mails we sent to and, I'm trying to contact you here. And yes, I used a public esp as our own mail server is on your blacklist 😉

We received the following reply to our application for the verizon whitelisting:

Your IP has been blocked because of spam issues or because your ISP indicates that it is dynamically assigned

Neither is our SMTP server's IP address dynamically assigned, nor is it currently listed in any blacklists we are aware of ( This mail server has been operating from this IP address since 2009 without any major spam related issues.

When trying to send an e-mail to the verizon, our mail.log shows the following error message:

544D4ADA184 2857 Thu Jan 7 01:19:17 our@email.address
(host[] refused to talk to me: 550-Email from OUR.IP.ADDRE.SS is currently blocked by Verizon Online's anti-spam 550-system. The email sender or Email Service Provider may visit 550 and request removal of the block. 160107)

We would really appreciate if you could escalate this problem to someone who can help.

Thank you very much.

Best regards

A. Thermophyle
