Exchange 2007 mail flow (DNS) issue

I have Installed Exchange 2007 (seem ok) and mail flow locally is fine (this is good)

I have purchased from DYDNS a DNS name, mail hop outbound and mailhop relay as I cannot buy a static ip address from my ISP

I have opened smtp port 25 on the router - test ok with a port checking tool.

When  I try to send a test message from any internal user of this exhange system to an external recipient (ie my yahoo a/c) the message does not arrive.

I have had  a look at the queue viewer the current state of the next hop domain is "Unreachable domain"


I realise this is vague but i am struggling to set up these connectors and would welcome some help.

Can you telnet to Yahoo's MX record on Port 25  and send an email through it?
You also need to make sure you configure an SMTP Send Connector from within your administration tool

You must create a sendconnector to be able to send mail to Internet.
