Hi everyone, Some users are reaching out to us telling they have issues connecting to our service because of incompatibility between the set of ciphers offered during the connection.
On our send, we decided to use the ciphers suggested by Mozilla on their SSL Configuration Generator (https://ssl-config.mozilla.org/) (level "Intermediate") but I'm aware it's more for the HTTPS connections that ESMTP / TLS. So maybe there is another set of ciphers recommended for creating secured connections in email that I'm not aware of. Do you have any recommendations for this or is the ones from Mozilla (Intermediate) is good enough? If you want to avoid loading the link, here are the ciphers suggested by them: Ciphers: ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-CHACHA20-POLY1305 Cipher suites: TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256 And we only accept TLS at v1.2 and higher. Thank you in advance.
