If you ever were looking for a replacement for Outlook Express (msimn), or for that matter, any good news + mail reader, this is it.

1. Doesn't open Windows Messenger by default. ( major PITA with msimn)

2. Color coding. Quoted messages (with > and >>) with different levels are coloured with different shades for upto 4 levels.

3. Great UI. One of the best you will see. Highly customizable. Great icons, treat to use. Fast, unlike the new blog + news readers.

4. Great Mail Viewer. Thread identification for Mails too (like GMail), gives you more access to what you are sending and your identity (unlike Outlook etc, every mail can be sent using one of the many mail accounts that you keep, and can customize all Mail headers like ReplyTo, Organization, Sender Name, Keywords ,X-Headers etc easily, which is the keyword here.)

5. NNTP. Awesome viewer. Subscribe different groups with different accounts, change them while sending mails without any fuss at all. Identifies abbreviations and tool-tips them :), scoring (havent used, i dont need it, but its a very good idea), hide signatures , hide quoted lines, it marks the thread as read if you move to the next one after getting bored reading one or more messages in the thread. Read raw message.
