Contacting them may not do a bit of good.  They will ask you to pay (up
front) for them to even consider taking you off their list.  I don't
think that with this guy's track record, that anyone really uses his
service as a reason to block mail.

Luke,

   FYI - www.rbls.org lists both of your SMTP servers as being
blacklisted by www.block.blars.org You may want to contact them and find
out why...
Here are the links to the reports
http://rbls.org/?q=208.4.66.22

Chris, Luke mentioned earlier in the thread that he was able to connect
via telnet to yahoo on port 25. 

Luke, if you're familiar with SMTP commands, I suggest you make the
telnet session again, but try to manually run through a complete
session, for
example:

220 YSmtp mta399.mail.scd.yahoo.com ESMTP service ready helo smginc.com
(Their response codes may not match mine exactly, but it should say OK)
mail from:<myaddress@xxxxxxxxxx> 250 Ok rcpt to:<yahooaddress@xxxxxxxxx>
250 Ok Data
354 End data with <CR><LF>.<CR><LF>
Subject: test message
Hi
.

Send the transcript of this session to the list if you can.

Does each location have its own Internet Mail Connector?  If so, are
both of those servers referencing the same DNS Server (if no SMTP
Gateway) or are they both forwarding mail to the same SMTP Gateway
server?  I would suspect that the Philly office has different routing
preferences and it sends mail using a different Internet Mail Connector
and probably uses a different DNS server.  Still either could be your
issue.

If you are listed as an open relay as Greg suggested, you may want to
attempt to telnet to yahoo on port 25 from each locations SMTP Gateway.
Your Philly gateway will probably have no issues connecting.  Your local
Gateway will most likely error out if it is being blacklisted....

The weird thing here is that your local gateway server is sending you
the 'delayed' notifications.  In my experience, most blacklisted domains
will not get a 'delayed' message, but rather a return from the recipient
domain stating that your mail was rejected....  For this reason, it
seems that you are unable to even establish connection from your local
domain to the recipient domain.

here's an interesting twist.. our network is connected by a frame relay
connection and our mail server in our philly office can send to yahoo,
and aol, etc. just fine but our mailserver here can't

Luke, it could be a dns issue as Chris mentioned, but the
www.dnsreport.com report for your domain indicated that you're an open
relay. I don't know if Yahoo rejects based on that, but I wouldn't be
surprised, given the volume of UCE they must process.
