Is it possible by API to insert messages in Google Groups?

Question

I'm building tools for maintaining our Google Apps for Business account.

Is there anyway to post content into a Google Group that isn't email? Ideally from within Apps Script but i'm in no way averse to using AppEngine or other exposure to API to achieve this end.

The essential use case is to be able to extract labelled email in a users account and replicat

Google just today announced the new Google Groups Migration API that allows you to import messages into a Google Group. The messages will not be sent out to group members via email but will appear in the group archive which sounds like your end goal:

The Groups service in Apps Script doesn't provide a way of directly posting content to a Google Group, though it has some methods for managing groups. You mentioned that you didn't want to do it via email, but if sending an email to the group programmatically (via Apps Script) would work, you can use MailApp or the Gmail service.
