Courier (formerly Calypso) Email, a Windows email client. I loved the way it handled multiple accounts, filtering, and auto-replies. Worked with POP3 and IMAP and had features that other clients lack such as blind send, configurable notifications per account, and export (which put any emails selected into a single text file, and dumped attachments to the file system and foldered them according to email ID.) Also, all account settings, filters, etc. and emails were stored in a ".box" file, so you could move or copy that single file from system to system. It lacked SSL/TLS which was the final death knell for it I think, as most email providers started requiring it.
