Small utility that will notify you when you have mail waiting on the POP3 server of your Internet provider (or Internet providers). Poppy can check multiple POP3 servers and check for new messages at regular time intervals.

Poppy needs a working internet connection and is typically used in combination with an ‘always on’ internet connection, such as a cable or DSL connection. It can be used with a dial-up connection, but that is not very effective.

Once you have started Poppy, you will see an icon in the so-called system tray or taskbar notification area. When Poppy detects that mail is available on any of the configured POP3 servers, it will let you know by changing the taskbar icon. Optionally, Poppy can also play a sound, execute an external program (like your e-mail program) or show a popup window containing a notification message.

In addition to its main purpose, which is e-mail notification, it can also display the headers of individual e-mail messages, preview the e-mail message source and delete individual messages from the POP3 server.

The dialogue that is used to display the headers of e-mail messages, uses selection rule to determine which e-mail messages should be selected. Once these messages are selected, you can delete them from the POP3 server. The selection rules are configured using the Options dialogue. This feature is especially helpful when you receive SPAM messages that you quickly want to delete from the POP3 server.
