Ask speakeasy to:

add an MX entry with priority 20 pointing to mail.vostok.pt
add an MX entry with priority 30 pointing to smtp.npc-usa.com
Ask to the provider of vostok.pt:
add an MX entry with priority 20 pointing to smtp.npc-usa.com
add an MX entry with priority 30 pointing to mail.vostok1.com
And that's it (from the DNS side).
wouldn't it be simpler, and less dns-polluting to use something such as:
npc-usa.com. IN MX 10 mx-us10.npc-usa.com.
npc-usa.com. IN MX 20 mx-vo10.npc-usa.com.
npc-usa.com. IN MX 30 mx-vo20.npc-usa.com.
vostoc.pt. IN MX 10 mx-vo10.npc-usa.com.
vostoc.pt. IN MX 20 mx-vo20.npc-usa.com.
vostoc.pt. IN MX 30 mx-us10.npc-usa.com.
instead of spreading MX'en across multiple domains etc.
if you have lots of inner-workings like that, using an administrative
domain might be useful as well.
anyhow - beond this, if you're still not catching on, I suggest you read
the mail-howto (http://www.tldp.org/HOWTO/)
