I have some emails which are been deleted as spam and the AgentLog files contains the section
... Sender Id Agent,OnEndOfHeaders,DeleteMessage,,MissingPRA,No valid PRA,
I would like to configure Exchange 2007 not to reject emails from this particular domain.
I thought it was a matter of using the PowerShell command
Set-SenderIDConfig -BypassedSenderDomains domainname
but this does not seem to make any difference.
The domain in question does not have any SPF record set.
