My postfix server receives email for several sub-domains of my-domain. All email addressed to one of the sub-domains is aliased to u...@my-domain.com <mailto:u...@my-domain.com>. For example:
a...@sub-domain1.my-domain.com <mailto:a...@sub-domain1.my-domain.com>=> u...@my-domain.com <mailto:u...@my-domain.com> d...@sub-domain1.my-domain.com <mailto:d...@sub-domain1.my-domain.com> <mailto:a...@sub-domain1.my-domain.com>=> u...@my-domain.com <mailto:u...@my-domain.com> g...@sub-domain2.my-domain.com <mailto:g...@sub-domain2.my-domain.com> <mailto:a...@sub-domain1.my-domain.com>=> u...@my-domain.com <mailto:u...@my-domain.com> 1...@sub-domain3.my-domain.com <mailto:1...@sub-domain3.my-domain.com> <mailto:a...@sub-domain1.my-domain.com>=> u...@my-domain.com <mailto:u...@my-domain.com> I use transport to pipe the email to an external application: u...@my-domain.com <mailto:u...@my-domain.com> etof: I would also like to archive a copy of every email, so I use an always_bcc always_bcc = arch...@my-domain.com <mailto:arch...@my-domain.com> But this doesn’t work “anymore.” I believe it used to work, but it’s possible I didn’t test properly in the past. I realize that “BCC recipients are not generated after Postfix forwards mail internally” Is the use of the alias and/or the transport considered an internal forward? If it is an internal forward, does anyone have any suggestions other than my external application
