Thank you for taking the time to answer in such great detail! You
described excactly my problem: the test profile is a trap and that is
good, so I recieve proofs of every delivery. That it is unfortunately
also in the reports I found by filtering by domain, just as you
described. So, if e.g. the delivery goes to 2 profiles and one is the
trap test profile, the opening rate is shown as 50% when the test
delivery was opened but not the real recipient. This messes up the
statistics from a customers...
