These instructions are useful if you just want to check email securely without logging in; the same effect can be had via the command line by SSH'ing in to mlug.missouri.edu and using Pine.
Instructions inside Netscape (all instructions refer to the image below them) :
Go to Edit, Preferences, Mail & Newsgroups, Mail Servers
Click on Add

Add mlug.missouri.edu (make sure you use mlug.missouri.edu, NOT www.mlug, nor by IP) to the list, and set it as an IMAP server. Enter your user name (same as your login name). Check email every so often and Remember Password are up to you . . . you can check or not check these, depending on your circumstances.

The only one below that you must check is the "Use Secure Connection (SSL)" box; the rest are optional.

Under the Advanced tab, settings should be exactly as below, but there's no need to enter the 3 boxes of "namespaces" as the server will automagically provide these. Once you've entered the options here, click OK.

When you check mail for the first time, this is what Netscape will show you (a self-signed security certificate for the
MLUG server). Follow the directions below, noting which radio buttons (if any) are checked.
For the first panel,
you only need to click Next.

Click Next.

"Accept this certificate forever", then click Next.

Do NOT click the "Warn"box; click Next.

Click Finish.

You should be able to read you email after completing the certificate process above (you'll only have to go through the above process during the first access on any machine, thankfully :)
This is very bare bones right now, but will be updated soon. Feel free to send any questions to the MLUG list and we'll try to answer them.
Best, John.
