I’m looking at selective nolisting — iptables rejecting connections to the primary MX for certain IP ranges, but if those MTAs are “smart” enough to be RFC compliant and fail-over to the secondary MX (which is actually the same machine as the primary, but listening on a different IP), then allowing the mail through.
As part of this, I want to be able to ex-post-facto examine the headers to determine if spam came through the primary or ham was blocked on the primary but came in the secondary. (Of course, there’s a chance of ham failing to fail-over to the secondary MX, in which case I won’t know about those messages, and users won’t know why they didn’t get expected ham… but hopefully that won’t happen much.) -J > On Feb 8, 2015, at 6:20 PM, Sam Varshavchik <mr...@courier-mta.com> wrote: > > Jeff Potter writes: > >> Is there any way to get it to be “by >> <URL:http://mx.example.com>mx.example.com [10.0.0.1:25]” or something like >> that?
