EzPop

Its main feature is to check your mail accounts every 1 to 99 minutes. When you have mail, EzPop will warn you by a mailbox image, a sound or a pop-up.
Want a quick look at this message you just received ? Double-click on the Mailbox and a window will open to let you read it. You can even reply from this window, save the attachment, or delete the message.
You can filter your messages, and avoid those annoying spam e-mails or huge attachments filling your mailbox.
