Is it possible to trace where an e-mail travels?

We switched ISP's. The new one is in a different country although the
domain name has remained the same. Normally, they say it can take up to
3 days for the new DNS Primary domain to update throughout the Internt.
It's been about a week now and for the most part, this update has taken
place.

Here is the order of events that took place (the real domain names have
been replaced):

1. We used 1 ISP for 2 domains: domain1.com and domain2.com. Both are
located in Israel. Both domains used the same mail server.

2. We move domain1.com to the USA and have it hosted by an ISP there.

3. The DNS update on the Internet happens quite fast but we wait about
a week for the new DNS Primary address to propagate throughout the
Internet.

4. People can send and receive e-mail on both domains to and from
anyone with one exception: if an e-mail is sent from the mail server on
domain2.com to domain1.com, it never arrives and no message is sent
from any mail server indicating any problem. Some people in Israel can
send an e-mail to domain1.com or domain2.com and it arrives. If someone
in Israel is using a different ISP, then their DNS is probably correct.
If they are using the same ISP, it is possible that there are multiple
DNS servers and the one they are using happens to be updated.

It would then logically appear that the mail server on domain2.com is
forwarding the e-mail not to the new ISP but has an old cached DNS on
its system somewhere.

Does this make sense? Is it possible from my computer to run a program
of some sort to determine where the e-mail is ending up at when sent
through the mail server on domain2.com? In other words, is it possible
to find out somehow (from my own computer) if the old DNS Primary name
is still being used by the domain2.com mail server?

Thanks for your insight
