Radke Land

The Thunderbird email client is a relative newcomer with some ancient (in internet timescales) roots. It grew out of the Mozilla project which was launched by Netscape (does anybody remember that browser?) in 1998. Configuration is pretty straightforward, just follow the screenshots. Note that until you permanently aceept mail.radkeland.org's certificate (details here), you will be prompted whenever you start the client.

Ok, on with the screenshots. In configuration one, name the account whatever you like. You can fill out the Email Address: and Reply-to Address: to be whatever you like. This may be particularly useful if you are using an email alias that you happen to like better than the default name you were given when you got an account here at Radke Land. Finally, note that your outgoing server may not be available until you've configured one (screenshots four and five).
Thunderbird Configuration One

Screenshot two has settings critical to getting your client working correctly (top half), and some general preferences (bottom half). Note that even though the checkbox for "use secure authentication" is not checked, your authentication is encrypted via the SSL link created before you actually log in (in otherwords, your username and password are never sent in the clear).
Thunderbird Configuration Two

None of the settings in figure three can break your email access, but it's worth talking about them, since there are peculiarities with IMAP. If you want a local (fast) copy of all of your email messages, put a checkmark in both of the top boxes. This will make it so that each email is only downloaded once. The reason they are not checked in this screenshot is that I use the same account from at least two different computers (on a daily basis). When I move messages from the client on one computer, the changes won't necessarily show up on the other if I've got the messages cached. There's no particularly easy way around this issue, since the Radke Land email server doesn't care where your client is connecting from. The lesson: Be confused, but not troubled.
Thunderbird Configuration Three

Thunderbird doesn't hide that you need to configure ingoing and outgoing mail servers. In fact, it makes it much easier to let you use a reliable outgoing server for all of your emails. This is the screen where you would add an ougoing server.
Thunderbird Configuration Four

As you can see from this final screenshot, setting up your outgoing server is just plain simple.
Thunderbird Configuration Five

Enjoy your use of Thunderbird, one of the nicest email clients I've used! And as always, if you have any question, feel free to email me.
