I'm about to sell my Macbook Pro and go full iOS. I'm wondering, though, how to empty trash in the Mail.app? I use iCloud, Gmail and Exchange (work) email accounts and none have an "Empty Trash" option. In OS X Mail I periodically select Mailbox>Erase Deleted Items>In All Accounts... and Mailbox>Erase Junk Mail. Are there iOS equivalents? Cheers, Steve.
