Hello. The webmail for the account contato@mirasul.com.br authenticates normally. However, in Thunderbird, IMAP on imap.kinghost.net:993 SSL/TLS connects successfully, and SMTP on smtp.kinghost.net:465 SSL/TLS also establishes a secure connection, but SMTP authentication fails. I have already removed the saved passwords, tested using the full email address as the username, and used the same password that works on webmail.
