I sent 2 messages to the list I'm on. On the first message I put myself in the Bcc field (that's what I usually do)
A Bcc: header really is not a thing, as far as an MTA is concerned. You have to go out of your way to make Exim do anything with a Bcc: header. Putting "Bcc" on a message you are sending (using an MUA, which is something external to Exim) *should* add the addresses you say there to the set of addresses passed to Exim in the SMTP "RCPT" commands, but not include them in the "To:" header list of addreses. It should *not* add a "Bcc:" header - the whole point of Bcc is to not leak those extra destinations of the message to every recipient. Now: will Exim de-duplicate message destinations? Yes, as far as it can. It's not perfect; there are situations it cannot. But it's quite likely for simple configurations. -- Cheers, Jeremy -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-users-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
