MySQL插入到，如果不存在，则具有双重条件

如果电子邮件地址不存在于列表\u email.email\u addr中，并且不存在于列表\u no\u email.email\u addr中，我正在尝试插入新记录

INSERT INTO list_email(fname, lname, email_addr) VALUES('bob', 'schmoe', 'bogus@bogus.com'), ('mary', 'lamb', 'hoe@me.com');
SELECT email_addr FROM list_email
WHERE NOT EXIST(
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

试着这样做：

 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)
