You may set up your account to automatically delete the contents of your Trash folder after every logout, or when the mail within the Trash folder is either one or two weeks, or one month old.
NOTE: Once the mail has been deleted from the trash folder, you will no longer be able to retrieve those messages. It's best to periodically check your trash folder for any accidentally deleted messages to ensure that you don't lose critical or necessary emails.
To edit your setting, please follow these steps:
1) Click on the Preferences menu located in the upper right hand of your account. The preferences window will open.
2) Click on General Settings underneath the Email Heading.
3) Scroll to the bottom of the window.
4) Underneath the Cleanup heading, use the dropdown to select the duration you'd like to keep the messages within your Trash folder before deletion.
5) Click Save in the top-left corner of the preferences window
