Mozilla Thunderbird

Tags: Networking

I obtain my Internet service from CenturyLink.

I have been using for many years Mozilla Thunderbird for my email as my much preferred email service provider.

Recently, the following message has started popping up after I compose an email in Thunderbird and hit the Send button:

“An error occurred while sending mail: The mail server sent an incorrect greeting: 5.7.1 [C18] RBL restriction: Blacklisted by Internal Reputation Service – 23.83.131.210.”

I reinstalled Thunderbird as a possible remedy. The problem persisists.

My vague understanding is that the problem lies with CenturyLink, and NOT Thunderbird. It MIGHT be that they don’t support Thunderbird any longer.

Before I contact CenturyLInk, I want to make sure that they are the right party to contact about the above problem. Getting a live person at CenturyLink to talk to is somewhat of an ordeal.

Thank you.

“Spamhaus ZEN 23.83.131.210 was listed.”

But you write “I have been using for many years Mozilla Thunderbird for my email as my much preferred email service provider.”

Thunderbird is an email program, not an email provider.

https://cleantalk.org/blacklists/23.83.131.210 lists it too.

-> Again, this is not a Thunderbird issue. It’s your email service which I can’t tell from the information given so far.

Thank you, Bob.
