In an ideal world, I'd have a single dnslookup router that happily delivered mail all day long. But host reputation is a fickle beast, and it's painful to have mail sit around deferred or frozen until I get our IP taken off the DNSBL list of the week.
As a solution to this game of whack-a-mole, I'm curious if I can configure Exim in such a way that it attempts a first delivery through the normal dnslookup router, and if the mail is rejected, retry with a router that sends it through an ESP (Mailgun in my case) which has way more IPs and resources to keep them clean. How might I configure my routers to ignore an initial 5xx response from the first router and attempt another (and maybe future) deliveries through an alternate router? Thanks!
