Because it didn't go through your old exchange server before and with the
advent of your new Exchange server your network guru blocked all smtp
going out except from that address. Want to try something weird? go to:
http://www.zmailer.org/mxverify-cgi.html
and in the first box put in a domain name, like yahoo.com
Pick the first MX record THAT SUCCESSFULLY COMPLETES A TEST. (Many people
leave their first MX record down to block spammers who don't like to waste
time trying down the list entries.)
I put in yahoo.com and the first mx record was mta5.am0.yahoodns.net.
Now, back on your i, put in the following at the command line:
telnet 'mta5.am0.yahoodns.net' port(25)
Now, all that stuff you saw at that website, like
EHLO
RSET
MAIL FROM:<postmaster@xxxxxxxxxxxxxxxx>
and so on you can enter from that screen.
But, if your network admin blocks SMTP you won't even get connected
If you have multiple IP addresses defined in NETSTAT *IFC then use iNav to
see which one that SMTP is bound to. For more information check:

I use the telnet commands above to do some rudimentary smtp testing.
