Google Apps Email Bounces for few uses

I have two domains Google Apps (for argument sake - a.com and b.com).

I have setup the mx records according to what Google recommended for both the domains.

I receive all emails on a.com and mostly all on b.com. I mention mostly as I have few set of users who complain that they get a message from mailer-daemon

This is the email they forwarded (they are using exchange IMO) to my a.com domain telling that their email to my other domain are not going through. This tells me that it may not be Google apps.

I see that their SMTP server is trying to deliver this message to itservicecompany.com - I am not sure who their are - they are not senders.

This question does not belong on SU. Recommend moving it to ServerFault. – BBlake – 2014-08-19T13:54:02.080

Looks like you moved the Email from other provider to Google Apps, just double check that the user is in fact using Google Apps and not your previously setup Mail Server. Since there are none of the Gmail IPs or Domains in the email that you posted. – Eduardo Romero – 2014-08-19T17:33:47.940

We have moved to Google Apps for more than a year now. It's not just with one user - it happens with all of them (very randomly - one in few hundreds). The same email goes to another domain which is hosted on Google Apps too. All MX records point to Google Apps recommended records. I am a bit stumped. – user378464 – 2014-08-20T04:18:05.413
