Eudora (32-bit)v5.0.2

Eudora has very strong message filtering functions. You can sort incoming or outgoing messages into user-defined mailboxes and automatically modify subjects and priorities and color-code e-mail based on different criteria. You can sort messages into mailboxes, forward e-mail to other locations or persons, send automated replies, and set alarms for when important messages arrive.

ESP (Eudora Sharing Protocol) is for sharing documents and discussion among a group of Eudora users, called a workgroup.

MoodWatch is a feature that warns users if their drafted e-mail contains potentially offensive language. It can also flag incoming messages that are potentially offensive. It graphically indicates the tone of on a graduated scale, using one to three red chili peppers (three chilies being the "hottest", of course).

Other features include: the ability to view and compose HTML e-mail, text formatting (including fonts, font sizes, styles, colors, layout options, and highlighted URLs), a message preview pane, support for multiple e-mail accounts, a customizable toolbar, customizable address book, nickname support (nicknames are for commonly used e-mail addresses), templates, POP server interaction, text searching, spell-checker, support for multiple signatures, MAPI support, IMAP4 support, LDAP support, UUEncoding, color-coded messages, return receipts, support for third party Plug-Ins, autoconfiguration, voice attachment support using PureVoice, statistics on the the e-mail you've sent and received, and inline editable signatures.

You can choose to run Eudora in one of three modes. A paid mode provides all the features, but you must register. A light mode is free, but provides you with fewer features. And a sponsored mode provides you with all the features, free, but with ads.
