Actually, MS Outlook is the one piece of Microsoft software that I really like. Granted, it's got some security holes, and it is, to some degree, bloatware, but it does have it's good features, too.
These include:
- Lets you access multiple POP3 accounts. Last I checked, Netscape Communicator only allowed multiple accounts if they were IMAP.
- Powerful "rules wizard" gives me complete control in sorting my incoming mail.
- "Auto-archive" feature lets me move old mail to an alternate file, with different settings for each folder. (IMHO, judicious use of this feature can really help cut down on Outlooks memory hoggishness)
