meassage_id Header

I use “Easy WP SMTP” to send emails with WP wp_email(), I would like to add into the email’s headers a “message_id” that can be read by the php imap_headerinfo() function;
I tried to add a standard header "message_id : id\n" in the wp_mail(...,$headers,...), but the function can not read it.
I’m not sure if it’s possible and eventually if I should work on php.int or “Easy WP SMTP”.
Any Idea?
