Configuring the Scan to E-mail environment

Overview

The Scan to E-mail is a function that transmits original data scanned on this machine as E-mail attachment.

Since this machine supports S/MIME and SSL/TLS encryption, and POP before SMTP authentication, security can be assured.

When the LDAP server or Active Directory is used for user management, you can search for or specify E-mail address from the server.

When using the Scan to E-mail, follow the below procedure to configure the settings.

1. Configure settings for connecting to the network such as setting of the IP address of this machine

   For details on configuring the setting, refer to [Configuring network environment settings] .

2. Configure basic settings for Scan to E-mail

   For details on configuring the setting, refer to [Configuring basic settings for Scan to E-mail] .

3. Set the following options according to your environment

   Purpose	Reference
   Communicate with the E-mail server using SSL/TLS	[Using an SSL/TLS communication]
   Use of SMTP Authentication when sending E-mails	[Using SMTP authentication]
   Use of POP Before SMTP Authentication when sending E-mails	[Using POP Before SMTP authentication]
   Addition of a digital signature by encrypting E-mails with S/MIME	[Using S/MIME]
   Search for an E-mail address using the LDAP server or Active Directory	[Searching for a destination using the LDAP server]

Reference

• If user authentication is installed on this machine, the Scan to Me function is available with which the login user can easily transmit E-mail to the login user's own address. For details, refer to [Sending to your address (Scan to Me)] .

Configuring basic settings for Scan to E-mail

Register the E-mail server (SMTP) address and the administrator's E-mail address.

1. In the administrator mode, select [Network] - [E-mail Setting] - [E-mail TX (SMTP)], and configure the following settings.

   Settings	Description

2. In the administrator mode, select [System Settings] - [Machine Setting], and enter the E-mail address of the administrator of this machine into [E-mail Address] (using up to 128 characters, excluding spaces).

   The E-mail address entered here is used as a sender address (From address) of E-mails to be sent from this machine.

Using POP Before SMTP authentication

Configure the setting if your environment requires the POP Before SMTP Authentication to send an E-mail.

The POP Before SMTP authentication is a function that performs POP authentication using the E-mail server (POP) before sending an E-mail and allows E-mail transmission only when the authentication is successful.

To use the POP Before SMTP authentication, enable the POP Before SMTP on this machine. In addition, configure settings for connecting to the E-mail server (POP) used for authentication.

1. In the administrator mode, select [Network] - [E-mail Setting] - [E-mail TX (SMTP)], and configure the following settings.

   Settings	Description
   [POP before SMTP]	Select [ON] to use the POP Before SMTP. [OFF] is specified by default.
   [POP before SMTP Time]	If necessary, change the waiting time until starting E-mail transmission after the POP authentication is successful. Depending on your environment, it may take time before the E-mail transmission is allowed after the POP authentication is successful. In that case, if a time period that is too short is specified, E-mail transmission may fail. [5] sec. is specified by default.

2. In the administrator mode, select [Network] - [E-mail Setting] - [E-mail RX (POP)], and configure the following settings.

   Settings	Description
   [E-mail RX Setting]	Select [ON] to use the POP Before SMTP. [ON] is specified by default.

Using S/MIME

The S/MIME is one of E-mail encryption methods. By using this function, you can add the E-mail encryption and digital signature functions to avoid the risk such as interception of E-mails or spoofing other sender.

To use the S/MIME, register a certificate on this machine. In addition, enable S/MIME on this machine.

1. Register a certificate used for E-mail encryption to the destination of E-mail transmission.

   For details, refer to [Registering E-mail Address] .

2. Register the certificate of this machine to be added to E-mails as digital signature.

   For details, refer to [Creating a certificate for this machine to communicate via SSL] .

3. In the administrator mode, select [Network] - [E-mail Setting] - [S/MIME], then configure the following settings.

   Settings	Description

The digital signature is automatically added without performing special setting before sending an E-mail. [Select when sending]: The user must select whether to add digital signature before sending an E-mail. [Do not add signature]: Does not add the signature. [Do not add signature] is specified by default.
   [Digital Signature Type]	To add digital signature when sending E-mails, select a digital signature type. [SHA-1] is specified by default.
