hi: I want to bcc all mails for archive purpose. one kind of mail is like below:
outside user (a...@gmail.com) mail to -> postfix alias with settings to forward outside (myal...@example.com) -> forward to outside user (b...@gmail.com) "always_bcc" and "recipient_bcc_maps" won't capture mails to "b...@gmail.com". "sender_bcc_maps" could capture the mail, but the whole mail didn't have any header information about "b...@gmail.com". can I write "sender_bcc_maps" to reveal the information about "b...@gmail.com"? or there are other method I can use to record the mail and envelope information?
