Ahh, so the message has not failed, its been delayed, if you look at your
SMTP queues do you see a lot of mail sitting in the queues, if you goto your
Exchange server and open a command prompt and type:

TELNET  mx1.mail.yahoo.com 25

What happens?

I have to say that we have seen this problem with many exchange sites. A lot
of admins (damn newbies) don't know to set their SMTP FQDN to the same as
their MX record in DNS, which is cause for an increasing number of ISPs to
reject mail, and for good reason.

Could you send the NDR, I just had a problem with my users not being able to
send to AOL users.  It turned out to be DNS issue reverse DNS lookup issue.
Once my ISP corrected this we could send to our AOL
clients again.

we recently upgraded our network to active directory and are running windows
2003 server with Exchange server 2003 and for some reason now everytime
someone tries to send to and addres @yahoo.com they get and NDR, and in our
previous environment we had no restrictions on who you could send it to..
and I am about 2 weeks into using E2k3 so I might as well have a blind fold
on..


any help is appreciated

Luke
