Chapter 2 Mail Service Maintenance 71

Retrying Undelivered Outgoing Messages

Sometimes the outgoing mail queue has undelivered messages. These messages are

properly addressed, but for some reason (destination server is down, the firewall was

blocking the outgoing port for SMTP, etc.) the messages aren’t sent. You can attempt to

send them again. Normally, the mail server will attempt to retry sending all by itself,

but you may want to trigger it manually instead of waiting.

To try to send an outgoing message again:

1 In Server Admin, select Mail in the Computers & Services pane.

2 Click Maintenance.

3 Click the Mail Queue tab.

4 Select the message to retry sending.

Hold down the shift key or the command key to select more than one message.

5 Click Retry.

Where to Find More Information

You can find more information about mail service in books and on the Internet.
