Is it possible to retrieve all valid email addresses for a domain via API?

[Thomas Witt]

Hi,

I am looking for a way to retrieve _ALL_ valid email addresses for a Google Apps Domain - including groups, users, aliases, etc.

Any ideas?

Best,

Thomas

That would require 3 API calls (possibly called multiple times):

http://code.google.com/googleapps/domain/gdata_provisioning_api_v2.0_developers_protocol.html#Retrieve_Account_Example  (User emails)

http://code.google.com/googleapps/domain/gdata_provisioning_api_v2.0_developers_protocol.html#Retrieve_Group_Example (Groups)

http://code.google.com/googleapps/domain/gdata_provisioning_api_v2.0_developers_protocol.html#Retrieve_Nickname_Example (Nicknames)

there's also no current way to "discover" all of the domain names in a Google Apps domain (secondary and alias domains). So you'd need to either know the secondaries or do your best to discover them.
