Mac mail is deleting emails from my Trash
When I delete an email from my inbox, it goes to Trash and I can see it there but after a month or so, it disappears.
Right now, they only go back to April 6th. I know I didn't physically delete them. It clearly is only keeping one months worth of deleted emails.
I want to keep all of my Trash emails until I delete them manually. I have the account settings for Deleted Messages set to NEVER.
What gives?
Mac OS X (10.7.5)
