Sending Mail with SMTP

You can send emails via the default SMTP server included with your Simple Hosting instance. You can also either use the SMTP server of Gandi Mail or an external SMTP server provided by a third party.

Note

It is necessary that you fill out the “from” field on the configuration page of your website CMS, otherwise your emails will not be sent out.

The Default SMTP Server

We recommend that you use the default SMTP server for basic mail exchanges or notifications such as password reset, account activation or any other notification not involving a high amount of mail traffic.

Warning

This option is not recommended for larger mail operations (for example, newsletters.)

PHP Instances

You will use the following configuration for PHP instances:

Third-party SMTP servers

This option allows you to send emails with no restriction. This is the best choice for larger mail operations and extensive email exchanges.

You can set up your own mail server or use the services of an external provider.

In this case, your provider will be able to provide you with the necessary configuration details. In any case, you must use one of the following ports:

Note

Port 25 cannot be used to connect to external email servers
