Hello Experts,  this is the scenario i  want to setup my exchange 2007 for receiving and sending e-mails with my external domain name, but i have .local domain with my 2008 server.
So i followed a tutorial,  

1.On the transport Hub  on the accepted domain   i entered my external domain name, and setted it   by default.

2.I created a send  Connector,  on the "space adress" i have set the "*" character for all domains
on the "network" tab i routed the messages  to my isp smtp, and checked use external lookup dns parameters on the transport server.

So my emails doesent wants to go out,   is it some other neceserray parameters for that configuration ?

>>I have a pop3 connector

It must be third party pop3 support is no longer in Exchange 2007?

>>but the port 25 is not forwarded on my exchange

to send out you need SMTP port 25 open outbound - with a configured send connector and the ability to resolve DNS
to receive in you nee an MX record pointing either to you or a host that will collect for you, smtp inbound to the either the public IP of the mail server or an IP address hat will port forward it to the mail server, and finally anonymous access enabling on the internet facing connector.

You also need to have an A and an MX record created on the public dns server that host the domain name. Set the address A record to point to the public ip address of your smtp server and the mx record point to the newly created A record i.e.:

MX      10       mail.mycompany.com
mail     A        150.223.12.10

make sure that your server is smtp is visible from outside your organisation with a test like

telnet mail.mycompany.com 25

it that connect from the outside you have one more step to succes.

yep its a third party as i have not sbs.

i have my domain name on a external isp who's providing e-mail and web support,
I use a pop3 connector for retrieving e-mails from that isp, and dispatching to the exchange mailboxes.

for sending e-mails its routed to a smarhost "my isp smtp"  but the message still doesnt go out.

i have read your tuto but its not my scenario.

Ok it seems that the problem  is the smarthost default port  for relaying.

because    the smarthost is   mail.c-c.ch    but the default port for smtp on my external isp is set on 587.
How can i change the default port for relaying ?

Fouded !

Open Exchange Management Shell and start by checking your Send Connector(s) :

   Get-SendConnector

You should get the name of your send connector(s) – like “Default Send Connector”.

If you haven’t messed up with the port configuration of the connector yet, it should be using the default port -25.
It is a good idea to confirm this with the command:

   Get-SendConnector | fl port

Then change the port with the command:

   Set-SendConnector –Identity “Your Send Connector Name” -Port 587

If you have only one Send Connector you can use that command too:

   Get-SendConnector | Set-SendConnector -Port 587

Of course, it is a good idea to check the final result again with:

   Get-SendConnector | fl port

Or even take a look at the full listing for the send connector:
Get-SendConnector | fl
