Mac OS X 10.0, 10.1: Mail Sends Same Message Repeatedly

Symptom

• A message remains in the Outbox after it is sent.
• The message is sent again each time other messages are sent.

Solution

This occurs if sent mail is saved in the Outbox folder. Instead, you should keep sent mail in the Sent Messages mailbox. Remove messages from the Outbox if necessary. If your sent mail is automatically being saved in the Outbox, follow these steps:

1. Select Mail Preferences from the Mail menu.
2. Click the Composing icon.
3. Choose Sent Messages from the "Save sent mail in" pop-up menu.
4. Quit and open Mail.

If the issue persists, restart the computer.
