Load up Eudora Light. Go to Tools and then Options. You should see something that looks like the screen shot to the right. Under the Pop Account field, put your e-mail address. You have the option to fill out the Real Name and Return Address fields but neither are required.

Click on Hosts in the left pane of the Options window and you should see something similar to the screen shot displayed here. The only field you need to modify here is the SMTP field. Type in smtp.dcn.davis.ca.us and you are set. Click on Ok to close the Options window. Go to File and then Check for new mail to see if Eudora is set up properly.
