always_bcc is implemented upon receving email, so that always_bcc = arch...@example.com
will send a copy to arch...@example.com, unless you have aliased that to something else. In that case, your BCC copy will be sent there. For example if you have a wild-card alias @example.com blah Then your BCC copy will be sent to blah, unless you also add an 1:1 alias to prevent that: # Everything aliased to blah @example.com blah # Except for arch...@example.com arch...@example.com arch...@example.com Wietse
