Unfortunately I was unable to find this information myself, so I am now asking 
here:

Does postfix forward the end of data characters from the client or does it 
replace them?
Is there any way to influence this behavior?

The message in the queue does not seem to hold any end of data characters,
which seems to indicate to me, that postfix sends its own.

I would be happy to receive information regarding this.

What do you mean end of data characters?
