Here's how I parse what you've written so far:

INVALID_COMMENTS = ("Σχολιάστε ή ρωτήστεμε σχετικά....", "")
SQL_COMMENT_FORM = "INSERT INTO users(mail, comment) VALUES(%s, %s)"

# insert guest comments into database if form was submitted
mail = form.getvalue('mail')
comment = form.getvalue('comment')
if "@" in mail and comment not in INVALID_COMMENTS:
    try:        
        cursor.execute(SQL_COMMENT_FORM % (mail, comment))
    except MySQLdb.Error as e:
        print("Error %d: %s" % (e.args[0], e.args[1]))
    else:
        mail = comment = None
