Need Toggle Proxy add-on to send emails

Thunderbird 52.0 and previous version. Several times a day outgoing SMTP messages fail to send. I discovered that if I toggle between "Auto-detect proxy settings" and "No proxy" when sending a previously blocked outgoing email, it will go out. A few emails later, I will need to switch back to the alternative proxy setting. The switch NEVER fails to solve the problem. Sometimes a failed send first fails to save; sometimes not!

I do not mind hitting the add-on icon (Toggle Proxy) to switch proxy settings, but I'd prefer to have Thunderbird function as intended. Hopefully, given the specific cause and effect described, there is a solution out there!

Thanks,

Bonnie Simrell

try disabling your anti virus email checker. I would bet it is the issue.

Thank you. An excellent suggestion. I disables my anti-virus/internet security program (Bitdefender). Delivery of outgoing emails still is randomly prevented, with SMTP server rejecting them or timing out. Changing the proxy setting **always** allows an outgoing email to be delivered as intended.

did you disable using windows safe mode with networking? Unfortunately these products are so entangled with the operating system it is really the only way to determine what they are and are not doing. I have seen many instances there folk chose to disable using the option in the software and it only sort of disables. This is particularly true of issues with routing and firewall components.
