If you have a domain on heroku and wish to receive emails on that domain then you need to configure your DNS to include MX records to tell the "internet" where to send emails.
First of all you need to make sure you are using a custom domain for your heroku website. By default you app will be
but we want it to be
First you need to claim myapp.com as your own. Go to a domain registrar such as GoDaddy or APlus and claim the name for yourself. It will cost you a few dollars to do so.
Then in the heroku dashboard for your app, add two custom addons.
- Custom Domains
- Zerigo DNS
Custom domains is simple you just add the names you wish your website to take
Zerigo DNS is a bit more complex. First you have to go back to your domain registrar service and tell them that the DNS for myapp.com will be handled by zerigo. You can do this by adding the zerigo name servers to your record.
Because Zerigo and Heroku are integrated all the settings are pre-configured for you when you add the zerigo add on for you app.
Now you have done this you will want to set up email support for myapp.com. Heroku does not have an add on to do this for you. Luckily you can easily do this with gmail though you have to set up a new account to do this.
Goto google apps signup and register for an account under myapp.com. Follow all the instructions for verifying that you own the domain name. This will involve either modifying a DNS record or placing some meta tags in your website.
You will notice on this website the meta tags
<meta name="google-site-verification" content="E7Npt5MsLN18NcKvW7NaTLgVbeJKN7DhTscOnssFU9E"/>
this is how I verified my site to google. Obviously do not paste the above into your website or I will be able to claim it as my own.
Once your google apps account is setup you then need to setup some MX records with Zerigo DNS to tell the internet to route your email to google.
Just add the following MX records to your account for myapp.com
Now you are good to go. And now you have
- free app hosting with heroku
- free DNS with Zerigo
- free email with gmail
