Check the settings of

Notify Senders =
Notify Senders Of Viruses =
Notify Senders Of Blocked Filenames Or Filetypes =
Notify Senders Of Other Blocked Content =

as they also affect what the senders get.

Sorry the sender notification settings seem a little complicated, I need to
balance the need to maintain backward compatibility with fine-grained
control, while still enforcing things like stopping everyone warning
senders about viruses by default.
