Can not get Thunderbird to connect to mail server
Been longtime user of Thunderbird. On 8/6/2026, Thunderbird refused to connect with the email service provided by DirectLink, Canby Telephone Association, Canby, OR. Have been working with Live Chat to restore connection. Have removed and reloaded Thunderbird. When I put in Security Setting under Connection security (SSL/TSL) and then test the setting, I get an error occurred connecting to mail.canby.com:993. DirectLink techs say they have done everything in their power to check their connection with Zimbra mailbox. Then they say, contact Thunderbird. I have been on Live Chat several times and they have checked my settings and my ipv4 settings. Tell me what I can do to get the email system to operate as it should. Clyde Hockman 503-592-4490
