When trying to send thunderbird emails I get the following error message, "Send error message, sending of the message failed, Peer's Certificate has expired, The configuration related to SMTP (my email provider) must be corrected.

This has just recently started to occur. How do I fix the problem?

Hello there.bile. We have read your message. We try to help you.


What antivirus do you guys have?

Try to turn of the hardcore antivirus.

And check your Smtp settings for that system. Mail domain settings.

Send me the rapport of this link below. https://www.checktls.com/TestReceiver (Scannedvirustotal)
