>From what you have written I understand that in most (if not all) cases,
each email has to be BCC-ed to "destination set", which consists of
{B,X,Y,Z,S1+office,S2+office}. Only emails to S1 and S2 don't, they are
BCC-ed only to B. Do I understand correctly?
So maybe you should try to use "recipient_bcc_maps" parameter for this,
without the need for too much aliasing?
I think that recipient_bcc_maps for each of O,X,Y,Z can be the above
"destination set", while the recipient_bcc_maps for S1,S2 would be just B.
Probably O should be then aliased to something like /dev/null, as there is
no actual recipient and all recipients are handled by BCC.
If I understand the documentation correctly
( http://www.postfix.org/postconf.5.html#recipient_bcc_maps ),
bcc_recipient_maps is applied only once, and the recipients mentioned there
don't get another copy of the same message ("To avoid mailer loops,
automatic BCC recipients are not generated after Postfix forwards mail
internally, or after Postfix generates mail itself.")
Can it solve your case?
