Sending Newsletters and Automatic Emails from Servers¶
Every managed server comes with a local SMTP server pre-installed. You can use it for sending application and batch emails. You can either connect to it via SMTP protocol using localhost as hostname and no authorization, or by calling PHP mail() function directly.
To increase the trustworthiness of your emails, we recommend signing them by DKIM key. More details about they way DKIM works and how to set it up are available in this article.
Sending batch and automatic emails is against the terms and conditions of the CloudMail service. You need to use the local SMTP on your managed server.
