Hello all,
I'm using exim 4.72, under Debian squeeze. I've been working on creating
routers that will add additional headers to our messages based on which
router they pass through. I however would like to create rate limiting
conditions that make decisions based on these added headers. How would I go
about configuring a ratelimit based on which router my message passes
through? Is it possible to create acl's within my routers or to set rules
that specify what acl to hit after passing through a router? Thanks in
advance, I have not be able to find a plentiful amount of documentation on
exim's ratelimit feature.
here's a snip it of my conf.d/routers/02_server_routers

# relay for. We do not ignore any target hosts here since delivering to
# a site local or even a link local address might be wanted here, and if
# such an address has found its way into the MX record of such a domain,
# the local admin is probably in a place where that broken MX record
# could be fixed.
