Hi,

 After installing Thunderbird 115, when sending an email, very often I will receive an email alert stating (see image - spanish screenshots):

Delivery failure: An error occurred while sending mail: outgoing server error (SMTP). The server responded xxxxx.domain.net Errro: timeout exceeded.

When I try to send to send an E-mail message I get the message "The mailserver answert : Unable to relay without authentication.. I checked everything also by the provider the settings are OK as far as I can see. Sending mail from my G-mail account is no problem! Hoping you can help me regards P.Rensel

I have installed Thunderbird on new computer. The first account that I set up works great. I then added second and third accounts. First account can send and receive email. Second and third accounts can receive email but when I try to send, I get a msg telling me that the msg size exceeds the global size limit of the server and to reduce the size and send again. And, to use port 587...which I am using. The msg is NOT too large, typically, it is, "This is a test."

See attached pic. I'd really appreciate help pointing me in the right direction.

Thanks.

I am unable to send emails from my Thunderbird email account. There is no "dashboard" or options bar displayed when I hit "reply" to a message. Nor is there such an options bar to create emails.

This is worrisome.

Please advice.
