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.
