I have 3 Thunderbird account. After updating recently mail is sent from only the top listed accounts. The other 2 get the error message "An error occurred while sending mail. The mail server responded sending rejected." How do I set up SMTP for the other 2 accounts? I could not find an answer searching Thunderbird forum.

The error indicates you don't have separate smtp servers for each account, or that the accounts are not set to send on the smtp with a matching User Name.
