Re: If it ain't broke
"Spam is not a thing caused by natural laws"
We'll have to agree to disgree on that one since human nature (i.e. some tits still click on links in spam and open attachments etc.) is a natural law.
I'd like a decent email client with built in key management and file storage options. I used to have a couple of add-ons for Outlook that did these things but every company I work at is different regarding what you can and cannot install.
If it was there by default it would be useful and that latter would especially be useful for all those expanding waistlines on the HDD's where users store all their attachments and important emails in the Deleted Items folder.
