If the only data you need in subdomain.domain1.com are the MX RR's, then 
you do not need to create / delegate a seperate domain.  In the 
domain1.com zone db file, do this:


subdomain       IN      MX 10 mailex1.somedomain.com.
subdomain       IN      MX 20   mailex2.someotherdom.com.


Now, mail addressed as specified above will go to the two mail servers 
listed in these MX RR's.
