    Hello :) This is discussed by Google at: Official Gmail Blog: Making email safer for you To clarify, are the emails in your Google account from the cPanel server showing this warning, or is this just a general question about your Google account? Thank you.

    What port number did you use when configuring your email account with Gmail? Ensure you use ports 995 for POP3 SSL, 993 for IMAP SSL, and 465 for SMTP SSL. Thank you.

    Sorry, you're getting me wrong. Actually email I send from my server to gmail shows that encryption: hostname did not encrypt this message. I want to know how can we encrypt the message with standard tls?

    Your server should utilize the STARTSSL command when initiating the SMTP session to Gmail. Please post the output from the following command on your system:
    telnet gmail-smtp-in.l.google.com 25
    Ensure to replace real domain names and IP addresses with examples. Thank you.

    I get the following output for this:
    # telnet gmail-smtp-in.l.google.com 25 Trying 74.125.138.26... Connected to gmail-smtp-in.l.google.com. Escape character is '^]'. 220 smtp.passthru Connection closed by foreign host.

    smtp.passthru

    Hello, Could you check with your service provider to see if they are intercepting outbound SMTP traffic in order to filter it? It looks like that's potentially the reason for this issue. Thank you.
