My intention is to setup a backup server copying all mail sent to or
emanating from a mail server to individual message files on disk for
archiving. Note that I do not have any control over the main mail
server.
The archiving bit seems to work. The very minimal config is below.
However I would like to capture the mail off a mirrored switch port.
I have used 'ip link set eth1 up' to turn the interface on, and I can
see traffic using tcpdump.
However, as I understand it, Exim needs an address in local_address to
operate. I imagine I need to set local_address to the address of both
the mail server and the isp's server through which the local server
sends all its mail.
I tried setting eth1 to have the same ethernet address as the mail
server (the fact that it has a duplicate address seems to be hidden by
the port mirroring function on the switch thank heavens), but no mail
came through Exim.
Thoughts and advice much appreciated,
Rory
