Delete an autoresponder when you no longer need to use it. If you use the autoresponder at frequent intervals, such as an "Out of Office" message, you can modify it to point to a nonexistent e-mail account, such as firstname.lastname@example.org, and then simply change the account name back when you need it again. Refer to Editing an autoresponder
To delete an autoresponder:
Click on the Autoresponders link in the Mail area.
Click on the Delete button next to the autoresponder that you want to delete.
