Our Exim server runs multiple users each of whom have multiple email accounts across a couple of smarthosts. Incoming mail, fetched with fetchmail, is added to /var/mail/<username> where a procmail script copies it (twice) to a maildir under ~/mail/inbox/ and ~/mail/inbox/.archive.inbox/. This way each user has a complete record of all incoming mail (in the archive) and can prune and (sub)file their inbox as they see fit.
Everything in ~/mail/inbox/ is served by dovecot (IMAP) so each user can access their mail with multiple different MUAs remotely. This has worked wonderfully for a while now. However, I would also like to archive all outgoing mail to ~/mail/inbox/.archive.outbox/ regardless of whether the user decides to also save the mail via their MUA into ~/mail/inbox/.sent. I know the users could achieve it via their MUA but not all support saving sent mail to multiple mailboxes (e.g. mutt without the fcc patch); and I want it to be independent of the MUA, outgoing mail* should be archived regardless. * = outgoing mail is defined by going through a smarthost (ideally). So, how can I archive all outgoing mail to ~/mail/inbox/.archive.outbox/? My attempt uses a system filter: system_filter = /etc/exim/system.filter system_filter_user = Debian-exim system_filter_group = Debian-exim system_filter_directory_transport = local_copy_outgoing local_copy_outgoing: driver = appendfile delivery_date_add envelope_to_add return_path_add maildir_format = true create_directory = true The system filter itself is as follows: unseen save $home/mail/inbox/.archive.outbox/ It seems as if $home is empty (because of the user being set to Debian-exim?) and thus nothing is saved. $sender_ident looks promising but doesn't look like it will work with MUAs using IMAP on a mobile device: unseen save /home/$sender_ident/mail/inbox/archive.outbox/ $sender_ident: When a message is received from a remote host, this variable contains the identification received in response to an RFC 1413 request. I figure I must be able to get at the sending user as local SMTP requires the user's username and password. Any help would be hugely appreciated. -- ## 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/
