Your MTA (Exim in this case, it seems) must already be aware of these virtual
user addresses since it accepts mail for them.  Adding a BCC to your MTA
config for these virtual users is the proper way to do this, not a sieve
script.  Not sure about Exim, but it's brain dead simple to do this with
Postfix' recipient_bcc_maps.  Since this occurs at the MTA level, users don't
have to be logged in and it's fully automatic.  It's not a 'forward' but an
automatic blind carbon copy to the specified address.
