I suddenly this week cannot send email using Thunderbird (v. 140.4.0esr (64-bit)). I receive email fine. I can send email using webmail with my provider. Error message in Thunderbird is: "Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-h2p-555359.sys.comcast.net resomta-h2p-555359.sys.comcast.net ESMTP server not available (62240/216.183.125.238)." My provider says the issue is not at their end because my server settings are correct. Outgoing SMTP port is 465, connection security SSL/TLS. Operating Windows 11 v. 24H2.

Are you using a VPN? If so, try disabling it.

I had not changed any settings before this issue started. I have been using a VPN with no problems, and I really would rather not disable it when working wirelessly. However, I had missed the response to tommymeisel regarding the same problem (trouble sending with Comcast); it suggested disabling the antivirus scan of outgoing mail. That seems to have resolved it for me. Appreciate any and all suggestions in any case!
