Pretty sure it is prefect fine to have different MX records for subdomains. example.com MX 10 mail.example.com. foo MX 10 mail.sub1.example.com. Bar MX 10 mail.sub2.example.com. Universities used to often have different MX servers for different departments/machines, though now it seems they are using external services for MX (maybe lucky, I checked five and all were using google or outlook for MX). -- "Are you pondering what I'm pondering?"
