Before You Begin
Procedure

- Select a Sky ATP Realm and click the pencil icon to configure
email management settings for that realm.
- Based on your selections, configuration options will vary.
See the tables below.
Table 239: Configure Quarantine Malicious Messages
Setting | Guideline |
|---|
Action to take | Quarantine malicious messages (the default)—When
you select to quarantine malicious email messages, in place of the
original email, intended recipients receive a custom email you configure
with information on the quarantining. Both the original email and
the attachment are stored in the cloud in an encrypted format. |
Release option | - Recipients can release email—This option provides
recipients with a link to the Sky ATP quarantine portal where they
can preview the email. From the portal, recipients can select to Release the email or Delete it. Either action causes
a message to be sent to the administrator.
Note:
If a quarantined email has multiple recipients, any individual
recipient can release the email from the portal and all recipients
will receive it. Similarly, if one recipient deletes the email from
the portal, it is deleted for all recipients. - Recipients can request administrator to release email—This
option also provides recipients with a link to the Sky ATP quarantine
portal where they can preview the email. From the portal, recipients
can select to Request to Release the email or Delete it. Either choice causes a message to be sent to the administrator.
When the administrator takes action on the email, a message is sent
to the recipient.
Note:
When a quarantined email is released, it is allowed to
pass through the SRX series with a header message that prevents it
from being quarantined again, but the attachment is placed inside
a password-protected zip file with a text file containing the password
that the recipient must use to open the file. |

Table 240: Configure Deliver with Warning Headers
Setting | Guideline |
|---|

you select to deliver a suspicious email with warning headers, you
can add headers to emails that most mail servers will recognize and
filter into spam or junk folders. |
SMTP Headers | - X-Distribution (Bulk, Spam)—Use this header for
messages that are sent to a large distribution list and are most likely
spam. You can also select “Do not add this header.”
- X-Spam-Flag—This is a common header added to incoming
emails that are possibly spam and should be redirected into spam or
junk folders. You can also select “Do not add this header.”
- Subject Prefix—You can prepend headers with information
for the recipient, such as "Possible Spam."
