When
a message is flagged by this filter, it is delivered to the junk email folder rather than the inbox. The
Recipient can manually move the message to the inbox and add the sender into its safelist if it ??™ s a
legitimate sender.
Sender Filtering
You use this feature to specify a list of email senders that you want to block receipt of email from. You
can configure the feature to block individuals, single domains, or entire domain hierarchies. You can also
specify how Exchange Gateway Services will respond when the blocked sender transmits a message to
this server. The following cmdlets can be used to view and configure SenderID filtering:
??‘ Get-SenderFilterConfig
??‘ Set-SenderFilterConfig
Sender ID
This feature, currently a proposed standard, was established to counter email domain spoofing and to
provide greater protection against phishing. You can use this feature to check the sender ??™ s Purported
Responsible Address (PRA) when the Edge Transport server receives an email. You can also specify how
Edge Transport server should handle messages from senders lacking an acceptable PRA. The following
cmdlets allow you to configure SenderID:
??‘ Get-SenderIdConfig
??‘ Set-SenderIdConfig
??‘ Test-SenderId
