After the latest Thunderbird update to 115.18.0 I can still receive emails but can not send. When I try to send, the following message appears in a box:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <martin.peros@bellnet.ca> sender rejected. Please verify that your email address is correct in your account settings and try again.

I have verified my account settings and all other data.

This may be a security warning. Possibly, if you post screenshots of both the incoming server settings pane and the SMTP server settings pane, some suggestions will be forthcoming.
