PP MailCheck lets you easily check your mails on a pop3 server, you can read it or delete it, and nothing is saved on your computer. This way is perfect to see what`s in your mail, before you download the mail with your normal email program. At the same time you can return mail. If someone sends you a mail, and you are not sure about it, just replay the mail, MailCheck can, if you want it to, insert details about the mail you got.
