I'm trying to figure out how to keep ALL of my deleted e-mails that are in my trash. I found out that if I delete an e-mail, that deleted e-mail is only in there for a couple days. I looked everywhere to try to figure out how to change that with NO luck. I've even tried sending an e-mail to "help" and I can't even do that.
The contents of your Trash and Spam folder are automatically emptied after a certain number of days.
