The same type of SSL cert that works for websites will work fine for email.

Howdy -- what is it that you'd like a hand with there exactly?

You can set SSL by enabling the SSL Website feature in Edit Virtual Server -> Enabled Features.

Once you do that, you can go into Server Configuration -> Manage SSL Certificates to manage/configure it.

Also, note that you can use a free Let's Encrypt SSL certificate for all that if you wish.

If you have any additional questions on that though, let us know what you'd like a hand with.

I find out is 3 months...so every thing is fine...but can you point me where and how to setup TLS for this email server using Postfix?

thanks

You may just need to copy the SSL Certificate into Postfix, using Server Configuration -> Manage SSL Certificates -> Copy to Postfix.

After doing that, are you able to access your email using TLS?

I am not sure is the answer yes or no but I am able to use my shopping cart sent out email through port 587....but when I do test email, it shows the green lock is unlock

below is the video shows my virtulamin settings and the result of the testing, please advise me the right direction how to make the green lock becomes "locked"

Copying an SSL cert into Postfix only configures it for receiving TLS-based connections. That doesn't cause it to use TLS connections for sending email.

To do that, try editing your Postfix config in /etc/postfix/main.cf, and there, add the following line to the end:

smtp_tls_security_level = may

And then restart Postfix with:

service postfix restart

After you do that, it should use TLS for sending email.
