MailBell - Version 2.04 MailBell is a utility that lives in your system tray and periodically checks email on POP3, IMAP4, MAPI and Hotmail-Email accounts. It can check multiple accounts and works on lans and permanent internet connections as well as with dial-up networking (where it detects when you go online). When new mail arrives the program can automatically start your mail reader, play a sound and/or display an unobstrusive notification window.
