Overview8
In today’s world there are many security threats to your network and the data that travels over it. Your Brother 
machine employs some of the latest network security and encryption protocols available today. These 
network features can be integrated into your overall network security plan to help protect your data and 
prevent unauthorized access to the machine. This chapter explains how to configure them.
You can configure the following security features: 
Sending an E-mail securely (See Sending an E-mail securely on page 66.)
Secure Management using BRAdmin Professional 3 (Windows
®) (See Secure Management using 
BRAdmin Professional 3 (Windows
®) on page 68.)
Note
We recommend to disable the FTP and TFTP protocols. Accessing the machine using these protocols is 
not secure. (For how to configure the protocol settings, see How to configure the machine settings using 
Web Based Management (web browser) on page 48.) If you disable FTP, the Scan to FTP function will be 
disabled.
 
Sending an E-mail securely8
Configuration using Web Based Management (web browser)8
You can configure secured E-mail sending with user authentication on the Web Based Management screen. 
aStart your web browser.
bType “http://printer’s IP address/” into your browser (where “printer’s IP address” is 
the printer’s IP address).
For example:
http://192.168.1.2/
cClick Network Configuration.
dEnter a user name and a password. The default User Name is “admin” and the default Password is 
“access”.
eClick OK.
fClick Configure Protocol.
gClick Advanced Setting of POP3/SMTP and make sure that the status of POP3/SMTP is Enable.

hYou can configure the POP3/SMTP settings on this page.
Note
• For more information, see the Help text in Web Based Management. 
• You can also confirm whether the E-mail settings are correct after configuration by sending a test E-mail.
 
iAfter configuring, click Submit. The Test E-mail Send Configuration dialog appears.
jFollow the instructions on-screen if you want to test with the current settings.
Sending an E-mail with user authentication8
This machine supports POP before SMTP and SMTP-AUTH methods to send an E-mail via an E-mail server 
that requires a user authentication. These methods prevent an unauthorized user from accessing the E-mail 
server. You can use Web Based Management, BRAdmin Professional 3 and Web BRAdmin (not available 
for DCP-7055W and DCP-7057W) to configure these settings. You can use POP before SMTP and SMTP-
AUTH methods for E-mail Notification, E-mail reports and Internet fax sending.
E-mail server settings
You need to match the settings of SMTP authentication method with the method used by your E-mail server. 
Contact your network administrator or your ISP (Internet Service Provider) about the E-mail server 
configuration.
You will also need to check SMTP-AUTH of SMTP Server Authentication Method to enable the SMTP 
server authentication.
SMTP settings
You can change the SMTP port number using Web Based Management. This is useful if your ISP (Internet 
Service Provider) implements the “Outbound Port 25 Blocking (OP25B)” service. 
By changing the SMTP port number to a specific number which your ISP is using for the SMTP server (for 
example, port 587), you would then be able to send an E-mail via the SMTP server.
If you can use both POP before SMTP and SMTP-AUTH, we recommend choosing SMTP-AUTH.
If you choose POP before SMTP for the SMTP Server Authentication Method, you need to configure the 
POP3 settings. You can also use the APOP method if needed.

Secure Management using BRAdmin Professional 3 
(Windows
®)8
Using BRAdmin Professional securely8
We strongly recommend to use the latest version of the BRAdmin Professional 3 utility or Web BRAdmin 
(not available for DCP-7055W and DCP-7057W) that are available as a download from 
http://solutions.brother.com/
. If you use an older version of BRAdmin1 to manage your Brother machines 
the user authentication will not be secure.
If you want to avoid access to your machine from older versions of BRAdmin
1, you need to disable the 
access from older versions of BRAdmin
1 from Advanced Setting of SNMP on Configure Protocol page 
using Web Based Management. (See How to configure the machine settings using Web Based 
Management (web browser) on page 48.) 
If you are managing a mixed group of older print servers
2 and the print servers with BRAdmin 
Professional 3, we recommend using a different password in each group. This will ensure security is 
maintained on the new print servers.
1BRAdmin Professional older than Ver. 2.80, Web BRAdmin older than Ver. 1.40, BRAdmin Light for Macintosh older than Ver. 1.10
