I am using Google Apps Premier Edition.

I want to create a disposable email address service and I want to catch all emails for a domain. This means that I should be able to catch all mails sent to an arbitrary userid and/or arbitrary domain and store them into a single Google Apps account.

For example, in a single account I want to get all mails sent to:

1) 2)

without requiring to do any extra configuration in Google Apps for abc or xyz. My app will download mails from this account and process accordingly.

I have figured out that I could do (1) by specifying a catch all email address.

Is the combination of both (1) and (2) possible?

I am a bit unsure... Do you mean that the "xyz" subdomain will be disposable? I will assume so.

As you say, 1) is easy and support is built in, but 2) requires you to register the subdomain as a separate google apps account, so if you mean for that to be disposable then you are out of luck. Once you have registered the subdomain the it will be a separate account, and you can set up a catch all for that too.

Subdomains with email accounts, such as also requires the appropriate MX (and SPF) records in DNS for that subdomain, what its parent has is irrelevant.

In short, no. I don't think what you want to do is possible.

Regarding question #1: It sounds like you want to set up MX records for a wildcard DNS domain (Something like *

Does this example from Wikipedia help you?

*   3600 IN  MX 10

This would set the MX record for and

Step 2 would be to convince Google Apps to accept email for any domain like * I'm not sure how to do that.

Google Apps for the domain will accept all mail for * and and map to the same account so there is nothing you need to do on the google side. The wildcard MX is all that is needed. – Mark Wagner Sep 8 '10 at 17:39
embobo, seems like your suggestion is not working.. I've added a wildcard MX record, sent an email to "" but Google responded with "550 550-5.1.1 The email account that you tried to reach does not exist". – jitbit Jun 19 '11 at 18:31
