Is there any way to route outgoing emails via smarhost but only if target MX has specific string in its dns name?
reason: google/gmail blocked some wide range of IPs recently and in it there is one of my servers. I got another IP from datacenter (which did cost me) and it is also blocked (its very similar, diffrent with only last segment). I want to route emails via my other server (smarthost). I'm doing this now for recipients @gmail.com but google hosts many domains, user domains (google apps) and there is no published list of those. Only way to find out if mail at domain is hosted at google is by looking at the MX records (for example gmail-smtp-in.l.google.com). So can I route to smathost only emails that would be sent to MX that ends with .google.com somehow? And yes, I tried contacting google at postmaster (this time and in the past) - they never ever reply.
