I have a little problem with the email server. If I send emails, it is shown as unencrypted (at the recipient). How can I fix it?

    Update the mail server to the latest version, which allows you to fill in the certificate you applied to enable ssl connection

        I have tried to paste lets encrypt SSL cert key and pem files, but it still shows message not encrypted when some one receives email. However it has helped to enable secure pop3 at port 995 and secure tls smpt at port 587.

        LetsEncrypt Finally Works with Mailserver too.

        Figured it out, we need to add these two lines in main.cf located at etc/postfix/main.cf
        Or you can also edit postfix config from mailserver settings and add these two lines of code:

        smtp_tls_security_level = may
        smtpd_tls_security_level = may

        Restart postfix and davecot services and it will remove security error message from email reception that server did not encrypt this message.

          i've added ssl certificate but still can't connect to SSL port 25, only can connect to unsecured connections.

          and theres problem with paging in email user list, can change to another page

            shm
            Please use the 465 port connection after adding ssl.
            Pagination issues will be fixed when the next version is released

                a year later

                aaPanel_Jose Whatif the letsencrypt SSL expired, will the email service auto replicate the pem file to the email SSL configuration.
                Or we need to manually copy and paste it?

                    by the way anyone know why I cant delete SSL from mail service.
