Gmail – Is it possible to set an account wide auto responder in Google Apps for Business (G Suite) Gmail

There are some very good services from Google for accomplishing user auditing on all Google services. Google basically stores stuff in an Atom feed that lets you play back changes.

This will help you get access to all data on any Google service how you requested it: Admin APIs

But if you are interested in real auditing tool, I recommend the Vault. Which is an extra 5 USD per month (total 10 USD per user account per month on the domain, and all users must be enabled for the vault).

There are other Google apps applications available on the Market that make use of the vault, or you can code your own.

MX records control only the server direction (i.e. messages sent to @example.com will be handled by the server located at 123.123.123.123). It's the local mail server that decides that admin@example.com and mail@example.com correspond to the same inbox. Google uses the term nickname for forwarded addresses.

In order to create a nickname for an existing user/inbox in Google Apps, you need to do the following:

1. Go to your Google Apps admin dashboard
2. Click on Organization and users in the blue navigation menu on top of the page
3. Click on the user, to which you want to assign a nickname
4. In the User information tab (the default one) click on Add a nickname (it's right below Email quota)
