Support » Plugin: Fast Secure Contact Form » [Plugin: Fast and Secure Contact Form] not receiving emails after 3.0 upgrade

  • The form was working fine. Then I upgraded to 3.0 and I get an error the site that says “the email could not be sent”. I have tried with and w/o an email in the optional “from” section. This is the error I get when I try to send a test email to a gmail account or an account on my domain:

    The result was:

  • Try using PHP mail function to send the mail instead of the WordPress
    mail function.
    On the plugin settings page you will find this setting: “Send E-mail
    function:”, try setting this to “PHP”, then test the form again. In some
    cases, this will resolve the problem.

    Did it work?

    In the contact form settings or the wp-mail?

    I changed the setting in wp-mail and received the same error. After changing to the php setting in the contact form settings I received the following error ON the site:

    Warning: mail() [function.mail]: SMTP server response: 451 See in D:\Hosting\2716753\html\abe\wp-content\plugins\si-contact-form\si-contact-form-process.php on line 364

    Not all mail sending problems have the same cause.

    I solved this by switching to a Lunix server. I read posts about it being more cooperative with wordpress. I use godaddy hosting.

    After the switch, the form worked on every page with the exception of the index. This was resolved by removing all the default godaddy files that were placed (by godaddy) on the index page of file manager.

    Very happy.
    Now I sleep.

    Changing the Send E-mail function: to PHP did the trick for me. Love this form Mike, will be donating soon, it’s the only one that I’ve gotten to work in WP reliably! Thanks

    More info for anybody else…

    Some servers require special settings before mail will send, they are setup this way to help prevent spam.
    My plugin has settings you can use to try to fix mail delivery problems, see this FAQ for help:
    Try step 4.
