POP Peeper geeft een seintje wanneer een e-mail zijn weg heeft weten te vinden naar je POP3-, Hotmail-, MSN- of Yahoo-account. Het programma werkt alleen op Windows-systemen met Internet Explorer 4+. Onlangs hebben de ontwikkelaars versie 2.3 uitgebracht en wordt geleverd met de volgende veranderingen:
mail.com webmail support Support for TLS/SSL (requires optional plugin) Password protection (administrator and individual account protection) New "Account" and "Message" modes Improved and more-customizable interface Messages stored between sessions Email client for each account (reply using a different email client) Conversion from HTML to Plain Text (for web messages, some pop3) New option to flash scroll lock when new mail is received Improved help system Fix: Win9x: Large POP3 messages (~7+ megs) might cause crash Fix: Multipart/Mixed is now handled correctly Fix: Multipart/Report is now handled to spec Fix: NT/XP: Large text messages were being truncated to 32K characters Fix: Hotmail: Invalid login error instead of generic error (internal hotmail change) Fix: Incorrectly marking messages as read (hide read messages, repeatedly toggling read state from message) Fix: Holding down delete for extended time may cause crash Large POP3 messages (~2+ megs) are now received faster Login error messages from server will be reported to user (instead of generic messages) Improved HTML->RTF conversions Optimized certain pop3 communications Improved replying capabilities using Email client Customizable keyboard shortcuts (via PPTweaker) Can now sort mail by the status (!) column Improved Shutdown Added Mozilla client support
