Which version of amavisd is that?  A 2.6.4 ?

Thanks. This doesn't indicate the message was quarantined.
But it does tell the message was bounced due to bad header
(empty line in a header section).

I don't see why the *destiny was D_BOUNCE, I can only guess
it is set to D_BOUNCE somewhere in you configuration files.
Check for final_destiny_by_ccat and final_bad_header_destiny.
Check also for the setting of $warnbadhsender.

$ egrep 'destiny|warnbadh|warnsender' \
    /usr/share/amavis/conf.d/* /etc/amavis/conf.d/*
