Please send emails to [edited] @gmail.com because I can't receive any emails at my regular email address. The error message that I keep getting when I try to send email from my regular email account ([edited] @optimumhealthrva.com) is attached.


screenshot of your SMTP settings is attached


mail provider = Optimumhealthrva.com ISP = Xfinity firewall version = Microsoft Defender Firewall  antivirus software = Microsoft Defender Antiviris 

operating system and version = Windows 11  Thunderbird version is 115.1.0 because, when Thunderbird quit working today, I uninstalled it and downloaded a new copy hoping that would make it work.  It did not.

click 'account settings, scroll down the left side to 'Outgoing servers SMTP, and do a screenshot there of the server. There should be one for each account.

All looks okay, but many email providers have changed requirements for more security. i suggest a first attempt would be to change STARTTLS to SSL/TLS. This article may help: https://www.xfinity.com/support/articles/update-your-xfinity-email-settings Otherwise, I have no other suggestions.
