Hi there, My boss need BCC all Manager's emails to him. But we have a problem that if the email send to boss, cc to Manager A and Manager C, then, my boss will receive 3 copies of the same email. Is it possible to add rules or ISP add feature that can scan BOSS already in list so not to BCC? As well as the email will just send to Manager A and Manager C, BOSS will just have one time BCC. Thanks for your help.
I've not tried it, but looks like dovecot's sieve can probably be made to handle that: http://wiki2.dovecot.org/Pigeonhole/Sieve/Extensions/Duplicate
