I think it should be:

school1 MX 10 mx1.duracom.net.
        MX 20 mx2.duracom.net.

just like the MX record for simplyschools.net itself.  You also need to 
contact duracom.net and get them to configure their mail servers to 
accept mail for the subdomains.

I'm not sure what the mail.school1 entry you suggested is supposed to be 
for, so I don't know whether you need it or not.  Is that your POP/IMAP 
server?
