Before you can configure and use SunMailer, you must configure PHPMailer. Go to: Administer > Site configuration > SunMailer > Configure SunMailer > PHPMailer settings The first task is to tell SunMailer where to find PHPMailer. This can be done in one of two ways:
  1. (Recommended) Add the directory containing PHPMailer to PHP's include path. Leave the PHPMailer path field blank. This method is required if you want to run SunMailer's tests with the SimpleTest module.
  2. Fill in the PHPMailer path field with the directory containing PHPMailer. On Linux, the command locate class.phpmailer.php can help you find this directory.
Basic settings contains some basic information SunMailer needs to send any email. Here, you will also make an important decision on how to send the email. By default, each subscriber receives an individual email (you must ensure your mail server can handle that many emails); you can also send one email bcc'ing all subscribers. Individual emails include a hash in their unsubscribe links to expedite the process of unsubscribing, and that option is required if the newsletter's content varies for each subscriber. If emails fail to send because too many recipients are bcc'ed, you can set split them into multiple emails with Maximum batch size. The next part, Mail settings, gives you an option to send mail using mail, sendmail, or SMTP. For SMTP, you can use authentication, SSL, and TLS. For Advanced settings, here is an in-depth explanation of some of these settings: To test the settings you have entered, enter an email address into Test email field and click the Send test email button.
