    Hello guys, I have a Cpanel WHM. I installed SSL for exim and dovecot services. I have a wordpress site and I want to send secured emails to users. I am using 465 SMTP port but emails are not encrypted. You can see log here pastebin.com/mfnrS60F. And email is here

    That doesn't prove the email is not encrypted that is simply showing your Wordpress plugins logging of the events to send the email.

    If you look at email's screenshot there is a red icon that shows email is not encrypted.

    Hello,

    You've configured SSL for email authentication, but this does not encrypt the actual email contents. You can use technologies such as S/MIME and PGP to sign, and encrypt, individual email messages through the email client itself, but it's not something that you'd configure through cPanel.

    Thank you.

    Doh, yeah I missed that.

    What plugin are you using for SMTP authentication?

    Also, switch to port 587 TLS

    So what is the point of installing ssl for email server?


    I use this plugin tr.wordpress.org/plugins/wp-mail-smtp/. I switched 587 TLS from plugin's setting. It sends email but it is not encrypted.

    It's to ensure the email account username and password are not transmitted in plaintext. The encryption of the actual emails needs to take place through the email client you are using with a technology such as PGP or S/MIME.

    Thank you.

    Hello,

    To clarify, have you installed that same WordPress plugin on another host and it encrypts the emails? As I understand, the plugin you are referring to includes an option to encrypt the SMTP authentication but not the actual contents of the email.

    Thank you.

    Hello,

    It is same result while I am using webmail (roundcube). It is not about wordpress plugin. Should cpanel has a feature about encrypt email contents? My problem is same with this Email without encryption

    Hello,

    Thank you for the additional information. It looks like what's in-question here isn't the encryption of the email contents, but rather the transaction itself. It's possible your data center is filtering outgoing SMTP traffic. Please run the following commands from the cPanel server and let us know the output:

    Code:
    telnet gmail-smtp-in.l.google.com 465
telnet gmail-smtp-in.l.google.com 25
    Thanks.

    Hello,

    Could you open a support ticket using the link in my signature so we can take a closer look and rule out any issues on the cPanel server?

    Thank you.
