I am new to Google Apps. Our domain has MX records pointing to Google Apps but I have not been receiving some emails in Gmail sent from the server. Where do I check to see if the emails have been received? Is there a log record in Google Apps?
Super administrators of Google Apps for Work, for Education, for Government and Unlimited editions could use the Email Log. See https://support.google.com/a/answer/2604578?hl=en for further details.
By the other hand, the Google Apps Toolbox could be used to check several issues. See https://support.google.com/a/answer/2520136?hl=en.
On the end user side, users could use the following Gmail troubleshooter: An incoming message was delayed or hasn’t arrived
