Answer 2

Replace

WHERE NOT EXIST(

With

WHERE email_addr NOT IN(

EDIT

Replace

SELECT email_addr FROM list_email
WHERE NOT IN
(
    SELECT email_addr FROM email_addr WHERE email_addr = $post_addr
) 
WHERE NOT IN
(
    SELECT email_addr FROM list_no_email WHERE email_addr = $post_addr
)LIMIT 1

with

SELECT email_addr FROM list_email
WHERE NOT IN
(
    SELECT email_addr FROM email_addr WHERE email_addr = $post_addr
    UNION ALL
    SELECT email_addr FROM list_no_email WHERE email_addr = $post_addr
)
LIMIT 1

Try something like this:

 INSERT INTO list_email($username.$rowname, fname, lname, list_email) VALUES(?,?,?,?,?)
     SELECT email_addr FROM list_email AS tmp
     WHERE email_addr NOT IN(
         SELECT email_addr FROM list_email WHERE email_addr = $post_addr)
         WHERE email_addr NOT IN (SELECT email_addr FROM list_no_email 
                                  WHERE email_addr = $post_addr)
     LIMIT 1;
