+1 We would need to see exactly how your powershell script detects that mail was accepted by the target PostFix server. I've written test equipment software, and one of the biggest thorns in such programming is to properly report testbed-induced failures.
For example, you could have told your powershell program to send mail, and your program received a 3xx, 4xx, or 5xx response. If your powershell script is submitting mail to exchange, again you need to monitor the result returned from exchange. Have you used the same test setup to stress-test other MTAs, and seen significantly different results?
