Sky ATP Email Management: Whitelists and Blacklists
Access this page from Configure > Threat
Prevention > Sky ATP Email Management and choose
either the Whitelist or Blacklist tab.
Use custom blacklists and whitelists to filter email attachments.
Before You Begin
- Read the Sky ATP Email Management Overview topic.
- Compile a list of known malicious email addresses or domains
to add to your blacklist. If an email matches the blacklist, it is
considered to be malicious and is handled the same way as an email
with a malicious attachment, blocked and a replacement email is sent.
If an email matches the whitelist, that email is allowed through without
any scanning.
- It is worth noting that attackers can easily fake the
“From” email address of an email, making blacklists a
less effective way to stop malicious emails.
Procedure
The procedure for adding addresses to blacklists and
whitelists is the same, although the results are very different. Be
sure you are adding the entry to the correct list.
- Select Configure > Threat Prevention > Sky ATP Email Management and choose either the Whitelist or Blacklist tab..
- Select a Sky ATP realm and click the + sign
to add a new entry.
- In the Email Sender field, enter the full address in the
format name@domain.com or wildcard the name to permit or
block all emails from a specific domain. For example, *@domain.com.
- Click OK.
