Scenario: I want to archive customer e-mail. Right now I am sending copies through a router via "manualroute" and "unseen" which works perfectly fine.
The only problem occurs when mails have multiple recipients like Bcc. The recipient of the mails must be rewritten to the same address (i.e. foo...@archive.tld) for the mailarchive to work – I use headers_add for adding "X-Envelope-To:" in order for the mail archive to distinguish them later. The problem is that Exim recognizes these mails as the same and either sends one mail with multiple recipients or (when I add "max_rcpt = 1") sends multiple mails - but these mails are all the same, they only have the "X-Envelope-To:" of the latest redirection. Debugging the process shows: "[duplicate, would not be delivered]" As far as I understand this is expected behaviour and only within pipes mails are treated differently. tl;dr: how can I force Exim to actually create single and unique mails instead of just ignoring duplicates? -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
