is it possible to set MX for a sub-domain to be different from the domain itself
ie a domain called mydomain.com might have the following mx
@ IN MX 10 mail.mydomain.com.
@ IN MX 20 spare.mydomain.com.
is it possible to change mx for a subdomain using $ORIGIN ? i know you can change www from this ie
$ORIGIN subdomain.mydomain.com.
www IN A 123.123.123.123
(this would set all www traffic to the specified IP)
but i have tried adding MX in the $ORIGIN but it didnt work
return mail error came back as "ERROR 550 Host unknown (Name server: subdomain.mydomain.com: host not found)
note (all domain names renamed to protect the innocent
)

It is possible to do as you say with the $ORGIN control statement.
Silly question.....is there an A record for the Mailservers in the correct domain ?

Why not:-
mydomain.com. MX 10 mail.mydomain.com.
MX 20 spare.mydomain.com.
subdomain MX 10 mail2.mydomain.com.
MX 20 spare2.mydomain.com.
As Jeff says, you need a valid A record within the zone for each MX record used unless you are using MX records from another domain e.g. mail.otherdomain.com

This will probably look awful...
$ORIGIN dev.
@ IN SOA ns0.dev. root.dev. (
2003022001 ; Serial
3600 ; Refresh
900 ; Retry
3600000 ; Expire
3600 ) ; Minimum
IN NS ns0
IN NS ns1
IN MX 5 excalibur
$ORIGIN legalex.dev.
@ IN MX 5 excalibur.dev.
urgh...
