I have taken the liberty to connect to your server, using openssl, i've
seen the following:
$ openssl s_client -CApath /usr/share/ca-certificates/cacert.org/
-connect mail.elisand.com:993
CONNECTED(00000003)
depth=1 /O=Root CA/OU=http://www.cacert.org/CN=CA Cert Signing
Authority/emailAddress=support at cacert.org
verify return:1
depth=0 /CN=*.elisand.com
verify return:1

Certificate chain
0 s:/CN=*.elisand.com
i:/O=Root CA/OU=http://www.cacert.org/CN=CA Cert Signing
Authority/emailAddress=support at cacert.org

i believe you should change two things. If the name you wish to use on
your clients is mail.alisand.com, then the certificate should read
CN=mail.elisand.com. Furthermore, it's always a good idea to provide the
chaining certificate path on dovecots side. Try using the ssl_ca_file
directive on dovecot's configuration.
