Solve 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
Information pages on page 176. Use the following
procedures to check if the SMTP and LDAP gateway addresses are valid.
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 product 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.
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.
