Hello,
My emails are no longer working
I receive the following message from Gmail (via Thunderbird):
"Sending the message failed.
The certificate authority of the peer is not recognized.
The configuration related to smtp.gmail.com needs to be corrected."
I compared it with other PCs ... I see nothing!!!
Thank you for your help
Best regards

imap.gmail.com port 993 SSL/TLS OAuth2
smtp.gmail.com port 465 SSL/TLS OAuth2

    Hello,

    The settings you indicated are correct.

    Have you enabled IMAP access in the Gmail webmail settings?

    What is well conceived is clearly stated,
    And the words to say it come easily.

      Hello Pierr10,
      Thank you for your response.

      After checking, the IMAP access is indeed working as you indicated.
      After testing, the Gmail emails work when accessed directly through Gmail (but not through Thunderbird).
      Another observation is that another address (SFR) also does not work with Thunderbird and returns the same message
      “The message transmission failed.
      The certificate authority of the peer is not recognized.
      The configuration related to smtp.sfr.fr needs to be corrected.”
      For now, I’m stuck...
      Thank you.
