Moving to a new hosting provider does not solve the problem.
Coincidentally I just moved to GoDaddy because they were less expensive than my current provider and they have a sale on hosting right now. Also, I was upset about recent performance problems and intermittent loss of service with my old provider.
But...I just ran into the problem with GoDaddy emails described above.
I sometimes use a package called "Form Tools" to process my CoffeeCup WFB forms. One of the Form Tools forums had a solution for the GoDaddy email problem with the use of their Swift Mailer module. I had to use Swift Mailer because some sites did not receive emails from php mail. Visit:
formtools.org for the forums and the package, if interested.
I you use WFB to handle the form, here's what the php code changes should be in user.cfg.php:
// What service is available for sending mail? Possible values are:
// - localhost [default] Server where the shop is installed, must be a Linux or Unix machine with sendmail
// - smtp A mail server of your choice that supports the standard SMTP protocol
//$user_config['mailer']['service'] = 'localhost';
$user_config['mailer']['service'] = 'smtp';
// Does the remote SMTP server need authentication?
$user_config['mailer']['smtp']['auth'] = true;
//$user_config['mailer']['smtp']['auth'] = false;
// Use this if the server needs authentication:
$user_config['mailer']['smtp']['user'] = 'webmaster@********.***';
$user_config['mailer']['smtp']['password'] = '**********';
// The address of the server
$user_config['mailer']['smtp']['host'] = 'smtpout.secureserver.net';
//$user_config['mailer']['smtp']['host'] = 'smtp.gmail.com';
// Connection parameters for a plain SMTP server
$user_config['mailer']['smtp']['port'] = '80'; // Yes, it
really is 80, also 3535 works here.
$user_config['mailer']['smtp']['secure'] = 'false';
// Connection parameters for a SMTP server that supports secure connections, such as smtp.gmail.com
//$user_config['mailer']['smtp']['port'] = '465';
//$user_config['mailer']['smtp']['secure'] = 'ssl';
This works for all my forms on GoDaddy that are handled by CoffeeCup. The settings are essentially the same for the Swift Mailer module in Form Tools.
If you need to play with the form data after it has been inputted, Form Tools is a good package to do that.
