Hi Rich,
I don't see anything expired in the certificate though.  There are 3 certs in my chain.

The mail server is valid from 12/29/2019 to 12/29/2020
Its parent "Sectigo RSA Domain Validation Secure Server CA" is valid from 11/1/2018 to 12/31/2030
Its parent "Sectigo" issued to USERTrust RSA Cert Authority is valid from 1/31/2010 to 1/18/2038

I'm on Windows 10 with the latest updates and the time is correct and Windows shows all three certs as  "This certificate is OK."

I can email you the cert or post more details.  Like I said this only started happening on this sylpheed client.  My other mail client on another device is not complaining.  Is there a debug or verbose way to run the sylpheed logger?

But the details of the certificate for my IMAP server are in the dialog, including the expiration date, and that is not set to expire yet for another six months.

My other email clients are continuing to connect to this IMAP server without issue of course.
