Nothing is wrong, the bounce was suppressed (i.e. should have
been generated according to a *_destiny setting, but was
considered better NOT to send it).

With infected mail, if a virus name matches
a @viruses_that_fake_sender_maps lookup, the sender is considered
very likely to be faked and bounce (=NDN) is not send,
i.e. is suppressed, effectively turning D_BOUNCE into D_DISCARD
for this message.

Similar mechanism applies for spam: is spam score exceeds
$sa_dsn_cutoff_level, then bounce is suppressed, turning
$final_virus_destiny D_BOUNCE into a D_DISCARD for this message.
