Users should always try to resend a memo for which they receive a Delivery Failure Report. To help users troubleshoot delivery failure, ask them to use Steps 1 - 3 below to send you a copy of their mail database. Sending you a copy of their mail database preserves the field properties of the reports, which you analyze as a means of troubleshooting.

1. The user creates a new mail database on the workstation. From the menu, choose File - Application - New. Be sure to use the current (MAIL6.NTF) mail template.

2. The user copies a Delivery Failure Report from the original mail file and pastes it into the new database.

3. The user attaches the new mail database to a mail message and sends it to you.

4. You open the mail database attached to the mail message and select a Delivery Failure Report.

The Delivery Failure Report identifies the reason the delivery failed and the routing path over which the message was sent. Use this information to further investigate the problem.

To troubleshoot mail routing or test mail connections, trace a mail delivery to test whether a message can be successfully delivered without actually sending a test message.

1. From the IBM® Lotus® Domino™ Administrator, click the Messaging - Mail tab.

2. If necessary, click Tools to display the tool bar.

3. From the tool bar, click Messaging - Send Mail Trace.

4. Complete these fields, and then click Send:

Field	Enter
To	The mail address of a particular user
Subject	The subject of the trace
Send delivery report from	Choose one: Each router on path to receive a delivery report from each router on the path Last router only to receive a delivery report from the last router only

Mail routing topology maps

Mail routing topology maps are useful to track mail routing problems between servers.

1. From the Domino Administrator, click the Messaging - Mail tab.

2. Choose one:

• Mail routing topology by connections
• Mail routing topology by named networks

From the Domino Administrator, click the Messaging - Mail tab, then select Mail routing status. You can also check for undelivered mail in the mail routing events view in the log file (LOG.NSF).

Mail routing event generators

Using a mail routing event generator, you can test and gather statistics on mail routes.
