I use the email address [email 2 removed]@interia.pl. The account is configured in Thunderbird on a Lenovo laptop. The laptop is protected by ESET Smart Security antivirus software. As recommended by Eset, I added ESET VPN to my protection. After enabling ESET VPN, the address doesn't configure. It requests a password. I receive messages that the server is disconnecting. Other addresses work. Disabling ESET VPN causes the address to work. This problem doesn't occur on my other Outlook email client. I would appreciate your help in resolving this issue. Sincerely, Paweł Jędrzejewski

Since update to version 145.0 I cannot send messages, when sending I get this message "Sending of the message failed. An error occurred while sending mail. The mail server responded: <*******@shaw.ca> sender rejected AUP#POL. Please verify that your email address is correct in your account settings and try again". Nothing has changed with account settings. Same problem on another machine that updated to 145.0. Any ideas what is broken?
