That depends - is postfix running as a daemon? If so, you need to  
find it's pid and do something like:

strace -p12345 -f -F

That should trace all the system calls of pid 12345 and any children.  
You then send the email in the normal way and see what it does with it.

If it's something you run from the command line, just pass it all the  
parameters you'd normally give it.

strace -fF postfix --somearg --otherarg

The -f -F tells it to trace any children.

You can pass strace extra parameters that tell it to record the  
output into a text file instead of dumping to the screen.. something  
like -o filename but best to check the manpage.
