Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
Recently thunderbird and Dovecot IMAPS cannot agree on SSL however Evolution, on the exact same system, is working fine with the same accounts. Tried recreating the Dovecot cert and also the thunderbird accounts from scratch. The OpenSSL raw client works fine as well. Would someone also confirm the openssl commands to create a selfsigned cert for dovecot imaps. They cert created does work with evolution; just not thunderbird. Thoughts?

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
Hello, This is a selfsigned cert. Both of the below methods were used. May I ask for 1. pointer to info setting up "intermediate certs" and where the certfile goes? The objective is to generate a self-signed cert and use it for just internal use with IMAPS dovecot. Separately, what are your thoughts as to why evolution works and thunderbird does not? Thank you, ==1 openssl genrsa -out key.pem 2048 openssl req -new -sha512 -key key.pem -out csr.csr openssl req -x509 -sha512 -days 365 -key key.pem -in csr.csr -out certificate.pem openssl req -in csr.csr -text -noout | grep -i "Signature.*SHA" && echo ==2 openssl req -newkey rsa:4096 -sha512 -x509 -days 365 -nodes -keyout mykey.key -out mycert.pem On 4/30/20 8:11 AM, Aki Tuomi wrote:> >> On 30/04/2020 14:49 hanasaki at gmail.com <mailto:hanasaki at gmail.com> >> <hanasaki at gmail.com <mailto:hanasaki at gmail.com>> wrote: >> >> >> Recently thunderbird and Dovecot IMAPS cannot agree on SSL however >> Evolution, on the exact same system, is working fine with the same >> accounts.
