Disabled PHP mail function

This notice is shown when you have selected to send your MailPoet emails with your own host in the Settings > Send With... tab, and we detect an issue on your site that could prevent email sending using your host.

This is generally due to any of the following reasons:

• You are using an email address that doesn't match your website domain. (e.g. Error: Could not instantiate mail function);
• PHP mail() function has been disabled on your website/host/web server;
• Your website/host PHP installation is not configured to correctly call the mail() function;
• You have no local mail server installed and configured.

In these cases, we highly encourage our users to send with MailPoet's Sending Service or another professional third-party email service provider instead of sending with their website's host.
