How do I create a mail server in Postal?

In order to send mail via Postal, you need two things: a mail server in the service and a domain linked to the service. You can create multiple mail servers and add multiple domains to each mail server if you wish.

If you already have a mail server in Postal and want to add a new sender domain, see this guide.

To create a new mail server in Postal, follow these steps:

1. Begin by logging on to Postal’s control panel.
2. If you do not have any mail servers already set up, click on the Build your first mail server button.
   
   If you have mail servers already set up, click the Build a new mail server button instead.
3. You are now asked to fill in the details of the mail server.
   Fill in the information as follows:
   
   Name: Enter a name for the mail server here, this is used to distinguish different mail servers within the service.
   
   Short name: This is created automatically if you do not enter anything in the field. Short name is used as a username in SMTP clients for mailing, so you can put anything here if you want (or let Postal autogenerate it for you).
   
   Mode: Leave this on ‘Live’.
   
   IP pool: Leave this on “Shared” if you have not chosen for your Postal Service to have a dedicated IP number.
   
   Then click the Build server button.
4. You will now be notified that your new mail server has been created.
   

You will now need to add one or more domains to your newly created mail server before you can send out emails via it. Follow the instructions in this guide to add a domain.
