We use Google site for our company and we want to be notified of page changes. Currently we use our own internal email server and not the one with google sites. So we have firstname.lastname@example.org the google sites is set to email@example.com. We also use Postini for spam filtering. I've tried a few different things without any real luck. I setup a mx record for google.company.com to point to postini.
1. Tried setting the domain in postini to strip sub domains.
2. Tried setting up an additional domain under our postini account for google.company.com
3. Tried using alias to point google.company.com to company.com both on the domain level and the user level.
All reset it unable to relay messages from postini.
Anyone done this before successfully?
