I have a postfix setup for a client domain "domain.com" wherein I have configured sender_bcc and recipient_bcc maps in this manner:
where a,b and c are regular users and d is their team leader. However the problem I have is that when d sends mail to either a, b or c, based on the sender_bcc and recipient_bcc rules, d gets a copy of the mail as well -- which is not required.
What I would like to know is that how do I restrict sender/recipient_bcc for a specific user -- i.e. is it possible for me to set a rule where mails between users on the same domain will not be affected by the sender/recipient_bcc rule.
Appreciate your inputs/ideas to implement this.
