Hi,

I've been facing some issues by sending emails with Thunderbird, followed every single step from the article https://support.mozilla.org/en-US/kb/cannot-send-messages, updated to the latest thunderbird version, check the SMTP outgoing server config, configured a new different SMTP server, verified if the right server was configured, deleted the SMTP password, uninstall and delete the root folder in C drive but still unable to send emails, i read that it could be a windows firewall issue so turned it of together with the antivirus and then tried to send emails, also in the windows firewall configures a rule allowing all outgoing traffic through port 25, 465 and 577, tried by enable the less secure app option in gmail account and actually i don't have new ideas about this issue, so you are my last option team, any idea or recommendation about how to fix this issue. Please find attached the current configuration of my thunderbird client

thanks in advance

Have you allowed the aneko.com.ar address to be use as a sender in your gmail account? Gmail require you to set such a thing up on their web site if you send more that a few emails with a non gmail account address.

Have you enabled or checked that cookies are enabled in Thunderbird. They are required for oAuth.
