Like this:

name = "Dan, III"

email = "some@example.com"

I am using this function and simply replacing comma with space (which
is incorrect):

(defun rcd-mailutils-mail-to (to-email &optional to-name)
  "Return list with \"mail\" program arguments with TO-EMAIL.

Optionally provide TO-NAME, the name of recipient of email."
  (let ((to-name (replace-regexp-in-string "," " " to-name)))
    (cond ((and (stringp to-name) (string-match "@" to-name)) (list to-email))
          ((not (seq-empty-p to-name)) (list (concat (rcd-rfc2047-encode 
to-name) " <" to-email ">")))
          (t (list to-email)))))

(setq to-name "Dan, III")
(setq to-email "some@example.com")
(concat (rcd-rfc2047-encode to-name) " <" to-email ">") ⇒ "=?utf-8?Q?Dan,_III?= 
<some@example.com>"

That email address will be later expanded to 2 email addresses when
given to sendmail, so anything after comma or before comma, becomes a
new email address with local hostname as sender.

I have tried this, but did not result well, same thing:

(concat "\"" (rcd-rfc2047-encode to-name) "\"" " <" to-email ">") ⇒ 
"\"=?utf-8?Q?Dan,_III?=\" <some@example.com>"
