Mergers and Acquisitions. Use a list of words or phrases to customize the 
Mergers and Acquisitions Codenames classifier, but it is not required. You do 
not need to use a regular expression. A match for the Mergers and 
Acquisitions Codenames or Merger Keywords classifier is a DLP violation.

For information on how to create a regular expression, see 

. For more information on how 

content matching classifiers detect DLP violations, see 

You have the option of limiting a DLP policy to scanning only messages based on 
specific information detected by AsyncOS. DLP policy scanning can be limited 
by the following information:

Senders and recipients

Attachment types

Message tags

You can limit the DLP policy to scan messages with specific recipients or senders 
in one of the following ways:

Full email address: 

user@example.com

Partial email address: 

user@

All users in a domain: 

@example.com

All users in a partial domain: 

@.example.com

You can separate multiple entries using a line break or a comma.

For an outgoing message, AsyncOS first matches the recipient or sender to an 
outgoing mail policy. After the recipient or sender is matched, RSA Email DLP 
then matches the sender or recipient to the DLP policies enabled for the mail 
policy.
