I'm in the process of testing Google Apps for our company. We only want around 10 people to have Google Apps in the beginning so we have split delivery setup. It goes a bit like this:
Email ¿ domain.com -> Google's Servers -> Google Apps users -> Gmail inbox
gapps.domain.com <- Non Google Apps Users
So far there are only two accounts setup in Google Apps. They were both address' that existed on the exchange server before. The mailboxes have since been deleted.
To get the exchange server to send internal mail to the Google apps users I had to add "aspmx.l.google.com" to the "Forward all mail with unresolved recipients to host" setting.
Everything seems to be working OK with that setup Google Apps users get their email no problem and the exchange users email is unaffected.
Exchange users can also send email to Google users.
However the problem comes when I try send email to my Google users after I have added them to distribution groups.
I though the easiest way to do this was to make a contact in active directory and set the email alias to an SMTP address: email@example.com. Then I added this contact to a group: firstname.lastname@example.org.
The delivery fails, every time.
I get this:
Your message did not reach some or all of the intended recipients.
Sent: 22/08/12 12:00
The following recipient(s) could not be reached:
User Google Apps on 22/08/12 12:00
A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator.
This persists until I remove the contact from active directory.
Google Apps is pretty useless to me unless I can add my users to distribution groups.
What's the problem here? Can anyone point me in the right direction?
Thanks for any help.
