Since we're talking about transport_maps here, my preference is DNS 
rather than transport_maps. I'd use DNS views such that each mail 
host sees the internal MX for each new domain rather than the MX as 
seen in the global DNS.

Sounds like you're also talking about relay_domains and possibly
relay_recipient_maps as well. You would still need a means of 
updating those, but that could be scripted and use SSH keys as 
suggested. Networked map types are possible for these, but in the 
case of relay_domains, not recommended.
