Hello, dear volunteer! I am experiencing a problem with Thunderbird (Version 128.8.1esr, 64-bit) in that I am unable to use it to send messages. Regardless of the message length (whether long or short), I consistently receive back the same error diagnostic, as shown in the image I have uploaded. Could you please help me with this issue? Thank you! Armando N.B.: For the time being, I have no trouble whatsoever in receiving messages.
