http://www.postfix.org/postconf.5.html#always_bcc
http://www.postfix.org/postconf.5.html#recipient_bcc_maps
http://www.postfix.org/postconf.5.html#sender_bcc_maps
The above bcc options lose envelope information, and may not be
suitable for a robust archive.
One solution is to use a regexp to encode the information something like
# recipient_bcc_maps = regexp:/etc/postfix/recipient_bcc.regexp
# recipient_bcc.regexp
IF !/archive.local.invalid
/^(.*)$/ $1archive.local.invalid
ENDIF
and use transport_maps to route mail for archive.local.invalid to
where you need it. Other variations are possible, such as using
virtual_alias_maps similar to the
above. http://www.postfix.org/ADDRESS_REWRITING_README.html

Another options is to use a content_filter that saves a copy of
everything that passes through. Amavisd-new can be convinced to
quarantine a copy of every message if you know the right incantation,
or write something yourself.
