You can also measure on the Exchange side by examining the SMTP logs (which you should have, despite the fact they're not enabled by default) and also the Application event log on the Exchange server. You can also increase the verbosity of the application logs on the Exchange server on a per-service basis. This KB article gives some elementary steps: http://support.microsoft.com/kb/257265 - you want to at least monitor the Transport service (and log SMTP, as I mentioned). Also, do you have Outlook installed on the Exchange server (which mucks up MAPI) or the SMTP service enabled in IIS on an Ex2K7 transport server? Both of those are no-nos.
