We have just migrated over to Exchange 2013 ..
We use a 3rd party application (Printbos) to send emails to local email accounts.
This worked fine when on Exchange 2010 but now after changing the SMTP address over we receive an error of :
501 5.1.7 invalid address
Having a quick look around it looks like our default receive connector has a blank default domain
The link below suggests this need to prefilled in with our Domain Name...
Do you agree this could be the problem ?
If so, Is it possible to find out what our default receive connection for mail is?
We have 5 connectors when doing a Get-ReceiveConnector via power shell.
They are :
Client Frontend MSEX02
Client Proxy MSEX02
Default Frontend MSEX02
Outbound Proxy Frontend MSEX02
