How can I setup Google Apps Email for a subdomain?

I have Google Apps setup for "domain.com". I'd like to receive mail at "user@mail.domain.com" how can I do this?

• You can set this up as either an alias domain on your existing Apps account or as a new Apps account, entering mail.domain.com as the domain in the set up process

  You will need to set up the correct DNS records against mail.domain.com.

  With an Apps domain alias all users are mirrored, i.e.:

  mail for user1@mail.domain.com will be recieved by user1@domain.com

  mail for user2@mail.domain.com will be recieved by user2@domain.com

  This is all done automatically for you once the alias is set up.

  To set it up as an alias:

  1. Log into you Google Apps dashboard

  2. Click Domain Settings

  3. Click Domain Names

  4. Click Add a domain alias

  5. Enter mail.domain.com in the textbox

  6. Click Continue and verify domain ownership

  7. Continue the process as you would an SLD

  x3ja : But watch out that when you send from user@mail.domain.com people you send to will get an "On Behalf Of" message displayed in certain clients - something like "From user@domain.com On Behalf Of user@mail.domain.com".

• There are many how-tos out there.

  You can find one here:

  http://paparadit.blogspot.com/2009/06/configuring-private-domain-email-with.html

  Basically you.

  1. Sign up for google apps.
  2. Setup your domain in google apps.
  3. Change the MX records of your domain to point to the google mail exchange servers.

  That is just a really high level overview of the procedure. Google apps provides lots of help in their FAQ site.

  Senseful : The question was specifically about how to do it with a subdomain if I already have Google Apps for a domain setup.
