If you don't want to use an SMTP "Y" proxy, you can use recipient_bcc_maps
with regexp tables, I believe examples are in the list archives.
BCC mapping via regexp or PCRE:
u...@example.net u...@example.net@archive.example.com
transport:
archive.example.com archive:[archive.example.com]:2525
master.cf:
archive unix ... smtp
-o smtp_generic_maps=...
with smtp_generic_maps stripping the appended domain, and now the
archive gets the same message envelope as the real mail flow.
The "advantage" of the "Y" proxy is that mail is never delivered
without being archived. With the above, mail might be delivered
first, and then the mail server disk crashes, and the archive copy
is never sent.
