I receive signed email. Signature for this email is generated with certificate that is issued from this authority
Sectigo RSA Client Authentication and Secure Email CA expiration 01.01.2031
09c0f2fc0bda94db5ffe2bdfa89942cfc9e0ad00
Above certificated is issued from root authority, that is trusted by Thunderbird.
USERTrust RSA Certificateio Authority expiration 19.01.2038
5379bf5aaa2b4acf5480e1d89bc09df2b20366cb
It should work, but Thunderbird is saying that digital signature is not valid.
If i open the same email using Thunderbird in windows everything is ok. What is the problem?
