First Look: Mozilla's Thunderbird 1.0First Look: Mozilla's Thunderbird 1.0

The interface is clean, simple and easy to use -- things make sense.

I can finally access the authenticated outgoing mail server of EarthLink from a hotel, the office, or anywhere without having to be on EarthLink's network.

(To prevent spammers from using their outgoing e-mail servers, some Internet service providers such as EarthLink block access to their outgoing e-mail servers to anyone not logged onto their network. For example, if I were in a hotel and I dialed up to EarthLink, I could use the outgoing server. But if I connected to the Internet via the hotel's wireless network, I could not access EarthLink's outgoing server.)

Eudora did not enable me to do this and I simply do not use Microsoft Outlook, which would have enabled me to do this.

I can read RSS feeds from within my e-mail client.

There's a global inbox that lets me control how I view all e-mail. For example, if I want to display all my e-mail across all of my accounts, but only from the last few days, I can.

I can multi-task. While a message is being sent I can go back to the main Thunderbird window and do other tasks. In Eudora and Outlook you can only do one thing at a time for the most part.
