How do I Block email sent from "user agent Sendy" in thunderbird
I keep getting email offers from a "User Agent Sendy" account. They keep changing the from address just enough to get by my filters. How do I Block emails from "User agent Sendy"? I have tried to make a custom filter for it but can not get the term "User Agent" to be accepted. I have tried syntax of; User_agent, User-agent and Useragent . Trying to use the term "User Agent" gives me an error in syntax. Really getting fed up with this spam!! Any help would be appreciated..
