Please help - I'm in the middle of an email sales campaign and losing sales. Windows 10 My email addresses are [email protected] and [email protected] I use Thunderbird email as my client between Rogers/Yahoo and had difficulties receiving or sending email messages with the Yahoo servers this morning. This has now been cleared up by Rogers Tech staff and I can now see and respond to my incoming emails through the Rogers/Yahoo website. However, I have lost the contact between Thunderbird and Rogers/Yahoo. The Rogers Technician changed my passwords this morning and I have done the same under "Passwords" in Thunderbird. The Yahoo server is set at pop.mail.yahoo.com, with SSL/TLS and OAuth2 My settings for [email protected] (my most important address) Outgoing traffic is: Server: smtp.broadband.rogers.com Port 465 Security SSL/TLS Authentication: OAuth2 Thanks - I'm desperate to resolve this server to client communication problem
