I was wondering if it would be possible to use a map for always_bcc that would bcc emails for some users and not others, and to bcc to a custom address for each user.
right now, I have always_bcc set to back...@covisp.net but I would like to set it up to something like: backups-user=domain-...@myslqldomain.tld But then only do that for some of the users and not use always bcc at all for the rest. I suspect I can do this with a simple regex match, but am not sure what happens if a map results in no return data for always_bcc. There’s nothing at http://www.postfix.org/postconf.5.html about using maps with always_bcc at all, so maybe not? (I use dovecot if that matters) -- First we must assume a spherical cow.
