A heads up

I had recently received a notification via e-mail that I had a message waiting here for me when I logged in. When I did log in there was no message to be found, however I THINK I've figured out what happend. I had sent an e-mail to someone and thinking this reply might have been from them and went to check if my e-mail was read. It had been deleted by the user, so I've come to the following conclusion. If you delete an e-mail from your inbox, that e-mail and all corresponding e-mails will be deleted. Anybody wishing to experiement with me on this, it would be greatly appreciated, because I don't want people to think I'm ignoring them! lol
