Connectors in Exchange server 2003
Posted on 2014-07-24
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 188.8.131.52.
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?
