    (I) Send all WordPress emails via SMTP
    I have tried several mail service like,,, most of the time I test sending mail it reported either connection refused, or timed out or things similar. Only two times it did pass the test and I registered successfully, but I didn’t know why because next time it failed again.

    (II)Use the PHP mail() function to send emails
    The tests are perfect. When I registered new user, it worked occassionally, as above, and failed most of time.

    I am totally lost. It seems to me more like an artwork than a technical issue. I am contacting godaddy support to see if they give me some clues.
