You can add to config.inc.php multiple SMTP email providers (your own hosting, Amazon SES, Mailgun, etc) and the SMTP class will try to send the email using the first available provider. If the first one fail, will try the next one and so on.
Setting up the contact form is not difficult. All default Smarty forms are already able by default to use the PHP. You can add multiple fields to any HTML contact form without doing anything else (PHP script will automatically handle all fields).
1. Open php/config.inc.php
2. Edit $config['sow.smtp:provider_email_list'] array
If you add multiple providers, duplicate any of the array (please pay attention to comma and punctuation). Set 'enabled' to true or false to enable or disable a specific SMTP provider.
Because this is Smarty, you have a config generator so you don't need to deal with plain PHP code.
Generate, save it and replace your php/config.inc.php
Note! You can also set multiple departments by using a <select> in your contact form. If you need multiple email destination for each department (marketing, support, sales, etc), you have to manually edit the config and follow the instructions on how to add a <select>.
$config['sow.smtp:provider_email_list'] = array(
/*
