hi all, im currently migrating from 2003 to 2010 (ive never set up exchange before)

ive manged to create and move some test accounts using exchange shell to the 2010 server

and even though this server cant receive yet as port 25 is still sent to the 2003 server i presumed id be able to send if the server had internet access (which it does)

i added my ISP's send connector to organisation configuration > hub transport > send connector

address space:
smtp.myisp.co.uk
scoped - unchecked

network:
use dns mx to route is selected

source server:
CH-EX (my server)

ive looked in the que viewer
quueID: CH-EX\unreachable
Last error: a matching connector cannot be found to route the external reciepient

can anyone help me out?

THanks

Address space should be * instead of smpt.myisp....
Link is for e2007, but it is the same

ok done that

i sent a test email to my hotmail account and got an email error back

SNT0-MC3-F10.Snt0.hotmail.com gave this error:
DY-001 Mail rejected by Windows Live Hotmail for policy reasons. We generally do not accept email from dynamic IP's as they are not typically used to deliver unauthenticated SMTP e-mail to an Internet mail server. http://www.spamhaus.org maintains lists of dynamic and residential IP addresses. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit http://postmaster.live.com for email delivery information and support

this means the external email sent though yes?

never seen that error before though, im not on a dynamic ip address either :|
maybe cos i havent forward the port yet?


so by using * as the external connector, where does it send my emails?

Cheers

Yes, the mail was sent outside, but it was rejected (spam protection).
Maybe you can try to use www.mxtoolbox.com web site to check if SMTP is working fine and if you are on some blacklist. (not likely)
Port forwarding could be the problem.
The other possibility  could be because your smtp header is not the same as rDNS setting on your external IP address.
Using * means "all domains" (except internal).
Mails for all external domains will be delivered to outside word using MX routing - it will be delivered directly to recipients mail server.
