Hello All,

I am running dovecot-2.0.9-8.el6_6.4.x86_64
how to apply SSL certificate to IMAPS

I configured: 10-master.conf

service imap-login {
inet_listener imap {
port = 0
}
inet_listener imaps {
port = 993
ssl = yes
}
}

10-ssl.conf

ssl = yes

ssl_cert = </etc/letsencrypt/live/fullchain.pem
ssl_key = </etc/letsencrypt/live/privkey.pem
ssl_ca = </etc/letsencrypt/live/cert.pem


local 10.100.100.6 {
protocol imaps {
ssl_cert = </etc/letsencrypt/live/fullchain.pem
ssl_key = </etc/letsencrypt/live/privkey.pem
ssl_ca = </etc/letsencrypt/live/cert.pem
}
}

ssl_protocols = !SSLv2 !SSLv3 !TLSv1

# SSL ciphers to use
ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!IDEA:!ECDSA:!CAMELLIA


but https://www.htbridge.com still blame me: we don't have SSL/TLS certificate on port 993

please help

thanks a lot

Cheers

It's usually as simple as creating a certificate (either a self-signed one, or buying a SSL certificate from a vendor), pointing your mail server's configuration file at the files containing the certificate and private key, enabling TLS, and optionally setting the mail server to deny logins which aren't using TLS/SSL.
