McAfee SaaS Email Protection Training Guide – Group Administrator Role

Proprietary and Confidential Page 6-5

Scenario:

 Spammer sends a message from a forged email address (spoofs a customer email address) of

an McAfee Customer

 Receiving MTA denies message because it’s from a spammer

 Receiving MTA sends a bounce back to forged senders email address (not original sender, but

forged sender)

 McAfee receives bounce to be sent to the ‘forged sender’, which is an McAfee Customer

 When Block Receipt of Bounce Messages is checked, McAfee will not forward this bounce

message to the forged email address; McAfee will send a 554 deny message to the sender of

the bounce

 Valid bounce messages will be processed as normal if the customer subscribes to Outbound

Email Filtering

Spam Content Groups

The Content Groups sub tab allows you to create content groups, add key words and designate

what action to take if an email contains content that is defined in any of these customized Spam

content groups.

Spam content filtering compares the key words in the Spam Content Group against the email

header, subject line and the message body.

You can define a different action for each Spam content group. The action in this window overrides

all other Spam actions.

Example: If the email has a medium likelihood of being Spam and contains content that is in a

Spam content group, the action defined for the Spam content group is applied.



Allow Spam content - causes the email to be accepted despite any other Spam filtering

McAfee

Checks the customer’s

policy and if Block Receipt

of Bounce Messages is

checked, do not pass the

bounce to the sender of

the forged message. Send

a 544 Deny message to

the sender of the bounce.
