Give your router box a real name, not just the (sub)domain name.

Keep this:

> rocky.sri.MT.net        preference = 0, mail exchanger = rocky.sri.MT.net
> rocky.sri.MT.net        preference = 5, mail exchanger = sri.MT.net

It's ok.

Make this:

> And, the important DNS stuff for my router box.
> sri.MT.net      inet address = 204.94.231.129
> sri.MT.net      preference = 0, mail exchanger = rocky.sri.MT.net
> sri.MT.net      preference = 5, mail exchanger = sri.MT.net
> rocky.sri.MT.net        inet address = 204.182.243.10

look like

router			IN	A	204.94.231.129
			IN	MX	0	router
			IN	MX	5	rocky

This just means that mail addressed directly to router.sri.MT.net will
be most preferably delivered to the host itself, or possibly backed up
for delivery at rocky (if necessary).

and add:

sri.MT.net.		IN	MX	0	rocky
			IN	MX	5	router

(You could omit the sri.MT.net. if you place this below the SOA and NS
records.)

Add

Cw	sri.MT.net.

to rocky's sendmail.cf, so it does accept the mail addressed to the
subdomain as its own.  Mail addressed to sri.MT.net will be stored at
router (on behalf of rocky, i.e. only for later forwarding) if rocky
is unreachable, but not further processed.

This should get you going.
