Topic: How to configure iRedMail to use a specific TLS cipher ?

Hello,

I am looking for information on how to run only a specific TLS cipher i.e TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384

I guess I need to make changes in /etc/postfix/main.cf but not sure what is parameter to specify a specific cipher.

Thanks

Search "cipher" in:

- /etc/postfix/main.cf
- /etc/dovecot/dovecot.conf
- /etc/nginx/templates/ssl.tmpl
