Smtp mail not being received

We have a strange problem. We use the Symantec SMTP gateway ver 3.1 for all incoming and outgoing emails. We have received complaints from different users that they are not receiving emails from certain email addresses. When we investigated we found that mail from domains starting with " x " are being bounced back , there are three domains we have identified based on our user feedback .. they are xerox.com, xpertlearning.com and xtra.co.nz.. These are the ones reported but it is quite possible that all domains starting with "x"are getting bounced.

Has anyone come across this problem and what is the resolution to this.?

Thanks

There was a filter in our Groupwise internet agent for blocking all incoming email from x*

Wonder who put it there.. time for a good change management system.. any ideas.?

Thanks a lot

My best idea is to limit access to that portion of GroupWise. It may be easier to do this if the GWIA is in a Secondary Domain and on a separate physical server.
