How to point mail.doma to another server

To point a mail domain to another server, you'll need to configure a few settings on both the sending and receiving servers. Here's a step-by-step guide to help you achieve this:

Prerequisites:

1. You have a domain (e.g., example.com) and a mail server (e.g., mail.example.com) that you want to point to another server (e.g., newmailserver.com).
2. The new mail server (newmailserver.com) has a valid MX record and is configured to receive emails for your domain.

Step 1: Update the MX record

Update the MX record for your domain (example.com) to point to the new mail server (newmailserver.com). You can do this by:

• Logging into your domain registrar's control panel (e.g., GoDaddy, Namecheap, etc.)
• Finding the DNS management section
• Updating the MX record to point to the new mail server (e.g., MX record with a priority of 10 and a value of newmailserver.com)

Step 2: Configure the sending server

On the sending server (mail.example.com), update the mail configuration to point to the new mail server (newmailserver.com). This will depend on the mail server software you're using (e.g., Postfix, Sendmail, etc.). Here are some examples:

• Postfix: Update the mydestination and relayhost settings in the /etc/postfix/main.cf file:

  mydestination = example.com
  relayhost = [newmailserver.com]:25

• Sendmail: Update the m4 file in the /etc/mail directory:

  define(`SMART_HOST', `[newmailserver.com]:25`)

• Exim: Update the router and transport settings in the /etc/exim.conf file:

  
  router:
  driver = manualroute
  transport = remote_smtp
  domains = example.com
  hosts = newmailserver.com
  port = 25

transport: driver = remote_smtp hosts = newmailserver.com port = 25

**Step 3: Test the setup**

Send a test email from the sending server (mail.example.com) to a recipient on the same domain (e.g., [[email protected]](mailto:[email protected])). The email should be delivered to the new mail server (newmailserver.com) and then forwarded to the recipient.

**Additional considerations:**

* Make sure the new mail server (newmailserver.com) is configured to accept emails for your domain and has a valid SPF record.
* If you're using a load balancer or a reverse proxy, you may need to update the configuration to point to the new mail server.
* If you're using a third-party email service (e.g., Google Workspace, Microsoft 365), you may need to update the DNS settings and mail configuration accordingly.

By following these steps, you should be able to point your mail domain to another server. If you encounter any issues or have further questions, feel free to ask!
