Does setting security.use_mozillapkix_verification to false make it work? (Use Config Editor... under advanced preferences)

Yes, setting security.use_mozillapkix_verification to false make it work. Thanks for the quick response.

Can you tell us which server it is, and/or provide details about the certificate?
I checked the certificates and found that the embedded crl url is unreachable and the IMAP certificate has expired, though the ca certificate is still valid. TB24 accepted the certificates after showing a security dialog. I'll fix that and try again but it will take some days till I have time for that.
