Inspector uses to evaluate email messages.
Use policies to determine the actions applied to detected threats and unwanted contents
in email
messages.
You can configure policies in Deep Discovery Email
Inspector to scan messages based on the message direction (inbound, outbound, or

exceptions reduce false positives. Configure exceptions to set the limits and actions
for email
encryption, or classify certain email messages as safe. Specify the safe senders,
recipients, and
X-header content, add files, URLs, IP addresses and domains, add URL keywords, or
specify senders
to bypass graymail scanning. Safe email messages are discarded (BCC and SPAN/TAP mode)
or
delivered to the recipient (MTA mode) without further investigation.
