  • TLS 1.2 outbound SMTP?

    When sending mail via outbound SMTP, can anyone confirm that the TLS level is 1.2?
    I could not find this in the documentation.

    Can you explain what you mean when you say TLS 1.2 outbound SMTP ? Usually, Mail Server with SSL certificate is also responsible for connection.

      Because we make use of Office 365, it is important that the TLS level is at least 1.2. Since microsoft is going to depreciate TLS levels 1.0 & 1.1 soon:

      So we need to know how Espo sends its emails and what TLS level is used.
      How to prepare to use TLS 1.2 for all client-server and browser-server combinations in Office 365 and Office 365 GCC after support for TLS 1.0 and 1.1 is disabled.

        TLS 1.2 is supported. But it's not EspoCRM, but your environment is responsible on a protocol version that will be used. It's unlikely that your env does not support 1.2.
