Connectors in Exchange server 2003

Hi,

I have a SBS 2003 with Exchange server 2003.
On that Exchange server, i have some connectors created to relay email.
My compreehension of this is:
I have a connector to the internet wich use the relay to a ip of the relay.net.vodafone.pt; anotehr relay which I called SBS connector SMTP which use the relay relay.net.vodafone.pt and another 5 connectors whit different costs which use the relay with a ip 195.232.244.5.
When I send an email internaly it uses the conector of the internet, because the address of the SMTP is my domain; whenever I send an email for any domain it uses the relay.net.vodafone.pt because the addess space created to SMTP is *; whenever I have to send an email to vodafone.com it uses one of the other 5 connectors. The problem is I can't send any email to the domain vodafone.com, we receive a NDR whenever I send an email to that domain, the message is:

A non-delivery report with a status code of 5.7.1 was generated for recipient rfc822;Joao.Carreta@vodafone.com (Message-ID <5E10BF2C12A95E45B0825C9489DF020301CE3788@ROCSBS-DC.rolloncell.local>).  
Causes: This message indicates that the sender was denied access or general access was denied.    
Solution: Check system privileges and attributes for the contact and retry sending the message.

So my doubt/question is, probably vodafone change anything on their site and my server can't contact them, it's possible i deactivate or stop those 5 connectors to force using the relay,net.vodafone.pt? If it's possible i can test and to see if i can send emails to that domain?

Thanks.

Best Regards.

Internal email does not go through the SMTP connectors at all.
You need to review the connector configuration, looking at the domains listed. Exchange uses the closest match first, cost is rarely used.
Do you really need all of those connectors? Most sites will have one or two at most, unless there is some complex routing going on.

Hi,

Simon, the problem i think wasn't the internal email, i assume internal mail those i send to my organization. I think i don't need all of that connectors, my question is that i have to test if i can disable temporarily a connector and how can i do that, to force the use of the other connector and see if that way i really can send email to that domain.

Could you help me on that?

Thanks.

Best regards.

Exchange 2003 doesn't have enable/disable capability on their SMTP connectors. Therefore the only way to confirm if things will work is to delete the connector.

In fact there isn't the possibility of disable the connector, the only way I can do that was alter the domain space for one that isn't used, and with that i can force to use the other connector.

Thanks.

Best regards.
