Hi Martijn,
our problem was, that one of our clients has a MS Exchange with the
setting "Don't accept empty sender addresses". Therefore the
notifcations weren't accepted.
This also means that they will not receive any bounce messages if they
also have this restriction on mail coming in from external.
They also don't receive self requested read confirmation and the like.
We also have such morons at the remote end and they all use Exchange.
Maybe the Outlook "Administrator" does manage E-Mail at this sites and
has never heard about any SMTP related RFC. I would not care about
them and for sure not breaking a RFC konform working system to get
them notified.

Andreas
