Overview

Mail Exchange (MX) records are DNS records that are necessary for delivering email to your address.

This article describes the steps necessary to adjust or connect to your MX records.

MX records

In simple DNS terms, an MX record is used to tell the world which machines accept incoming mail for your domain and where emails sent to your domain should be routed to. Most DreamHost customers host their mail service at DreamHost and all the required mail-related DNS records are created automatically after adding addresses to your domain in your panel.

You can also switch a domain's mail service between DreamHost, Gmail / Google Apps, or somewhere else entirely.

Who controls my MX records?

Your MX records are controlled at the company where your Nameservers are pointed. If your domain is using DreamHost's nameservers (you can check this at http://whoisweb.dreamhost.com), then all DNS changes (including custom MX records) are made in your DreamHost panel.

If your domain is not using DreamHost's nameservers, all DNS changes (including custom MX records) must be done at the company that hosts your nameservers. If you want to use regular DreamHost-hosted mail service with a domain using non-DreamHost nameservers, you can set up custom mail DNS records at your outside DNS provider using the mail DNS information from your DreamHost panel. See below for details on how to find these records.

Changing your MX records domain

MX records control where emails for your domain are routed and sent for delivery. Be sure that the email addresses you want to receive mail at are properly set up and working before changing the MX records to direct mail to the new location. If you change the MX records before setting up those mail accounts, or make an error when changing the MX records, emails sent to you may bounce back to the sender or be lost.

To change your MX records domain:

  1. Navigate to the (Panel > ‘Mail’ > ‘Custom MX’) page.
  2. To the right of your domain, click the Edit button.
    On this page you have several options:

Regular DreamHost Email: This is set by default. All the MX and other mail DNS records are automatically created to send your emails to DreamHost's servers. You can use the (Panel > ‘Mail’ > ‘Manage Email’) Link: https://panel.dreamhost.com/index.cgi?tree=mail.addresses& page to configure your domain's email addresses, both fully-hosted and forward-only. Note Box: If you’ve previously hosted your email outside of DreamHost and wish to now host email with DreamHost, you’ll see a button titled Make me regular now!. Clicking this will change your MX records back to DreamHost.

Google Apps for Business Google Apps lets you use email addresses on your domain with accounts on Gmail's servers. All the MX and other mail DNS records are automatically created to send your emails to Google's servers. You must sign up with Google Apps and configure your domain's email addresses using Google's control panel. Any DreamHost-hosted mail accounts will remain active but existing old emails may not be saved. Additionally the (Panel > ‘Mail’ > ‘Manage Email’) Link: https://panel.dreamhost.com/index.cgi?tree=mail.addresses& page will no longer display or let you configure them. If you want to host your email with Google, click the button titled I’m ready to use Google Apps now!.

Mail Mirror

Mail Mirroring lets you set one domain to automatically match another domain's email addresses. If you set domainMirror.com to mirror domainOriginal.com, all the email addresses you have individually set up on domainOriginal.com will automatically work for domainMirror.com. This feature can only be used if domainOriginal.com is using DreamHost-hosted mail service. If domainOriginal.com is using Anti-spam#Enabling_anti-spam_filtering Anti-spam filtering, you must enable it for domainMirror.com as well.

Custom MX Records

You can also enter fully custom MX records to direct your domain's mail to wherever you like. Use this if your mail service is hosted by a different provider and you want emails delivered to your mail accounts there. Your domain's mail provider will give you the MX records to enter here. (They may also give you Custom_DNS#Custom_A_Record A records or Custom_DNS#Custom_CNAME_Record CNAME records to add as well.) Any DreamHost-hosted mail accounts will remain active but existing old emails may not be saved. Additionally the (Panel > ‘Mail’ > ‘Manage Email’ Link: https://panel.dreamhost.com/index.cgi?tree=mail.addresses& ) page will no longer display or let you configure them. Leave the "...still check my email..." option un-checked to ensure emails are properly delivered to your custom MX records server. To use custom MX records with an external spam filtering service that sends all emails back to DreamHost for delivery to your mail accounts hosted here, use the Mail_Service_Provider Mail Service Provider instructions.

Checking your DreamHost email after switching to custom MX or Google Apps for mail service

NOTE: When you switch a domain's mail service away from DreamHost your DreamHost-hosted mail accounts will still remain active but stored emails may not be retained. Be sure to backup all your stored emails before switching.


Webmail can be used to login to your DreamHost mail accounts, but the webmail.yourdomain.com address no longer works. Instead you can use:


For POP3 access and/or to setup a mail client program to download emails to your computer, the server name mail.yourdomain.com no longer works. Use these steps to determine what server name to use:

  1. In the DreamHost Control Panel, click the "Account Status" link in the top right corner.
  2. Look for the Email Cluster.
  3. Find your cluster in the table below.
  4. Use the server name for the incoming server in your mail program.
Email Cluster Server Name
homiemail-sub3 sub3.homie.mail.dreamhost.com
homiemail-sub4 sub4.homie.mail.dreamhost.com
homiemail-sub5 sub5.homie.mail.dreamhost.com
homiemail-master homie.mail.dreamhost.com

Finding MX records for regular DreamHost mail service

Any domain in your DreamHost account can use regular DreamHost-hosted mail service. If the domain is not using DreamHost's nameservers, the mail-related DNS records will not be automatically active for the domain. You'll need to manually setup those records in the place where your domain's DNS is managed.

All the mail-related DNS records are automatically created in the DreamHost panel when a domain has email addresses setup in the panel's Manage Email page. You can find them in the same place all the other current DreamHost DNS information for the domain is, in the panel's Manage Domains page behind the DNS link for the domain.

There are two types of mail-related DNS records. MX records tell senders where emails for you should be delivered to. A records are used by your mail program when you connect to the mail server to view your inbox or send out emails. DKIM also uses DNS records with the "domainkey" name.

Enter all those records into the system where the domain's DNS is hosted and managed, the place to enter DNS information for the nameservers the domain is using. DNS information published on the domain's nameservers is seen and used by the whole internet, and putting those DreamHost mail-related DNS records there will get regular DreamHost-hosted mail service going for the domain.
