Hello,
We have in main.cf always_bcc = zz...@xx.com and our domain is xx.com
For specific 2 recipients of our domain, we don't want always_bcc to
be implemented. ie. if a mail is addressed to a...@xx.com (our domain
only), mail should not be Bcc to zz...@xx.com. similarly if mail
recipient is d...@xx.com (our domain only), mail should not be Bcc to
zz...@xx.com. For all others always_bcc to continue.
So, in summary, main.cf
always_bcc = zz...@xx.com
recipient_bcc_maps=regexp:/etc/postfix/regexp_recipient_bcc
#regexp_recipient_bcc
#/etc/postfix/regexp_recipient_bcc
a...@xx.com a...@xx.com
d...@xx.com d...@xx.com
Whether the above configuration will enable to get desired results?
ie. always_bcc should not work for a...@xx.com and d...@xx.com and
instead the mails are delivered to a...@xx.com and d...@xx.com only.

I don't think that will work: if you try it I think you will find you
get two copies of the email to a...@xx.com and d...@xx.com and still get
all mails copied to zz...@xx.com without achieving the aim because the
copy will alzo go to zz...@xx.com i.e. these are all cumulative
configurations.
You will need to eliminate the always_bcc configuration since you don't
always want all email to be bcced. You should only have the
recipient_bcc_maps configured.
Since this map is searched according to the search order indicated here
https://www.postfix.org/postconf.5.html#recipient_bcc_maps you could try
to map the more specific addresses to /dev/null and have a domain wide
bcc for the rest.
In order to do it and depending on how your domains are configured you
might need a local alias in the aliases file to send mail to /dev/null
file, e.g.
devnull: /dev/null
Then you can use that as bcc destination for those addressed that should
skip bcc copies.
#/etc/postfix/regexp_recipient_bcc
a...@xx.com devnull
d...@xx.com devnull
@xx.com zz...@xx.com
Postfix will still generate bcc messages for emails to abc and def but
they won't actually get sent out.
