I get this message when I send an email through Thunderbird: An error occurred while sending mail: The mail server sent an incorrect greeting: 554 5.7.1 RBL Restriction: Blacklisted by Internal Reputation Service - 127.0.0.2.
What is causing this message to appear? It just started our of nowhere. Thanks.

Sounds like your email provider got blacklisted for distributing spam messages. You should talk to your email provider.
This has got nothing to do with Thunderbird.
