Ask the subscriber to check that their mailbox is not full. If their mailbox is full, they cannot
send messages until some messages are deleted.
•
Ask the subscriber to check the format of the message address. If the FQDN after the @
symbol does not match the FQDN of CallPilot 100/150 configured to this mailbox, the
message is rejected.
•
Ask the subscriber to verify that no attachment is empty. An empty attachment causes the
entire message to be rejected. Delete the empty attachment and try sending the message again.
Test whether you can ping CallPilot 100/150:

At the DOS prompt, type:
ping <CallPilot 100/150 FQDN>
2
If the response is “request timed out,” then type:
ping <CallPilot 100/150 IP address>
Note: If there is a reply, then the CallPilot 100/150 FQDN has not been properly configured to
your Domain Name System (DNS). Contact your DNS administrator for assistance.
3
If there is no reply, verify that CallPilot 100/150 can be reached on your LAN. Contact your IS

Non-delivery notification
The subscriber receives non-delivery notifications for messages.
1
Ask the subscriber to verify that they have a valid attachment type.
2
Ask the subscriber to make sure that their mailbox is not full.
3
Ask the subscriber to make sure that they are addressing the message correctly. See “Address
Formats” in the online Help.

Ask the subscriber to ensure that they are attaching only VBK or WAV files to your messages.
Desktop Messaging does not accept any other file types.

If the subscriber is sending to a remote location, ask the subscriber to verify that the address is
valid and still exists.

Ensure that the subscriber has the capability to dial the number. Refer to the CallPilot
Manager Set Up and Operation Guide.

Verify that the remote server is responding by issuing a network command on CallPilot 100/
150. Internet Mail clients cannot send or receive WAV files.
