[Solved] Prevent notification email from going into junk

Hi,

For all subscription confirmation email and new comment/reply notification email, somehow it always end up in the recipient's junk mail.
Is there any way to prevent this?

Of course I am aware that we can ask the recipient to add my email to the Safe List but that can only be done if the recipient checks his/her junk mail.
I am looking at ways to prevent the mails from going into the Junk/Spam folder at all.

Thanks..
