[E-mail TX Setting]

When sending E-mails from this machine, set this option to ON (default: ON).

[E-Mail Send]

When using the Scan to E-mail function, set this option to ON (default: ON).

Using this function allows you to send the scanned original data as an E-mail attachment.

[E-mail Notification]

When using the E-mail notification function, set this option to ON (default: ON).

If a warning occurs on this machine that instructs the user to add paper, replace toner, or resolve a paper jam, it can be sent to a registered E-mail address. For details on the E-mail Notification function, refer to Notifying a Warning Occurrence or Consumables Replacement Period by E-mail.

[Total Counter Notification]

When using the total counter notification function, set this option to ON (default: ON).

Using this function allows you to send counter information managed by this machine to the registered E-mail address. For details on the Total Counter Notification function, refer to Notifying Counter Information by E-mail.

[SMTP Server Address]

Enter the address of the E-mail server (SMTP). Use one of the following formats.

• Example to enter the host name: "host.example.com"

• Example to enter the IP address (IPv4): "192.168.1.1"

• Example to enter the IP address (IPv6): "fe80::220:6bff:fe10:2f16"

[Port No.]

If necessary, change the port number of the E-mail server (SMTP) (default: [25]).

[Connection Timeout]

If necessary, change the time-out time to limit a communication with the E-mail server (SMTP) (default: [60] sec.).

[Server load reduction transmission method]

Select the sending method to reduce the load of the E-mail server (SMTP) (default: [OFF]).

• [Binary Division]: Divides an E-mail with the specified size. [Binary division Size]: Enter the size to divide an E-mail.

• [Stop Scan TX when maximum limit is exceeded]: Stops sending an E-mail when its size exceeds the specified maximum value. When specifying the maximum value, select [Limit] in [Max Mail Size], then enter the maximum E-mail size allowable for the E-mail server (SMTP) in [Server Capacity limit].

[SSL/TLS Settings]

Select the method to encrypt communications with the E-mail server (SMTP) (default: [OFF]). This option supports SMTP over SSL and Start TLS.

[Port No.(SSL)]

If necessary, change the port number for SSL communication (default: [465]).

This option is available when [SMTP over SSL] is selected for [SSL/TLS Settings].

[Certificate Verification Level Settings]

To validate the certificate during SSL communication, select items to be verified.

• [Expiration Date]: Confirm whether the certificate is within the validity period (default: ON).

• [Key Usage]: Confirm whether the certificate is used according to the intended purpose approved by the certificate issuer (default: OFF).

• [Chain]: Confirm whether there is a problem in the certificate chain (certificate path) (default: OFF). The chain is validated by referencing the external certificates managed on this machine.

• [Expiration Date Confirmation]: Confirm whether the certificate has expired (default: OFF). The expiration date confirmation is performed in the order of OCSP (Online Certificate Status Protocol) service, and CRL (Certificate Revocation List).

• [CN]: Confirm whether CN (Common Name) of the certificate matches the server address (default: OFF).

[SMTP Authentication]

When using SMTP authentication, set this option to ON (default: OFF).

[SMTP Authentication Method]

Set the SMTP authentication method to ON.

[User ID]

Enter the user ID for SMTP authentication (using up to 64 double-byte or single-byte characters).

[Password]

Enter the password for SMTP authentication (using up to 64 single-byte characters, excluding double quotation marks ").

[Domain Name]

When the SMTP authentication method is Digest-MD5, enter the domain name (realm) (using up to 253 single-byte characters).

When there are two or more domains (realm), enter the domain name. When there is only one domain (realm), no entry is required. The domain name is notified from the E-mail server (SMTP) at the initial communication, and communication is automatically performed using that domain name.

[Authentication Setting]

Select whether to synchronize the SMTP authentication with the user authentication of this machine (default: [Set Value]). This item is necessary when the user authentication is installed on this machine.

• [User Authentication]: Uses the registered user's user authentication of this machine as authentication information for SMTP authentication.

• [Set Value]: Uses values entered at [User ID] and [Password]. If SMTP authentication fails because the user who sends an E-mail does not match the user specified in [User ID], select [Bulk setting] in [Change From Address Setting] so that the same E-mail address is applied in From/Sender/Envelop-From. Enter the E-mail address to be applied in [From Address]. If an option other than [Bulk setting] is selected in [Change From Address Setting], the same E-mail address cannot be applied to From/Sender/Envelop-From, so the E-mail address of this machine's administrator is applied to Envelop-From.

[POP Before SMTP]

When using POP before SMTP, set this option to ON (default: OFF).

• [POP Before SMTP Time]: If necessary, change the waiting time until starting E-mail transmission after the POP authentication is successful (default: [5] sec.). 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 an insufficient time period is specified, E-mail transmission may fail.

[E-mail RX Setting]

When receiving E-mails on this machine, set this option to ON (default: ON).

[POP Server Address]

Enter the address of your E-mail server (POP). Use one of the following formats.

• Example to enter the host name: "host.example.com"

• Example to enter the IP address (IPv6): "fe80::220:6bff:fe10:2f16"

[Login Name]

Enter the login name used for POP authentication (using up to 63 single-byte characters).

[Password]

Enter the password for POP authentication (using up to 64 single-byte characters).

[Connection Timeout]

If necessary, change the time-out time to limit a communication with the E-mail server (POP) (default: [30] sec.).

[Port No.]

If necessary, change the port number of the E-mail server (POP) (default: [110]).

[APOP Authentication]

When using APOP Authentication, set this option to ON (default: OFF).

[Enable SSL]
