Solving e-mail problems

If you are unable to send e-mails by using the digital-send feature, you might need to
reconfigure the SMTP gateway address or the LDAP gateway address. Print a configuration
page to find the current SMTP and LDAP gateway addresses. See

Configuration page

. Use

the following procedures to check if the SMTP and LDAP gateway addresses are valid.

To validate the SMTP gateway address

Note

This procedure is for Windows operating systems.

1. Open an MS-DOS command prompt: click Start, click Run, and then type

cmd

.

2. Type

telnet

followed by the SMTP gateway address and then the number 25, which is

the port over which the MFP is communicating. For example, type

telnet

123.123.123.123 25

where "123.123.123.123" represents the SMTP gateway

address.

3. Press

Enter

. If the SMTP gateway address is not valid, the response contains the

message

Could not open connection to the host on port 25: Connect

Failed.

4. If the SMTP gateway address is not valid, contact the network administrator.

To validate the LDAP gateway address

Note

This procedure is for Windows operating systems.

1. Open Windows Explorer. In the address bar, type

LDAP://

immediately followed by the

LDAP gateway address. For example, type

LDAP://12.12.12.12

where

"12.12.12.12" represents the LDAP gateway address.

2. Press

Enter

. If the LDAP gateway address is valid, the Find People dialog box opens.

3. If the LDAP gateway address is not valid, contact the network administrator.
