Select "Settings" from the "Special" menu in Eudora. In the new window, scroll to the option titled "Personalities":

Select the "New" button to the right of the "Personality:" field to create a new email profile:

In the "Real Name:" field enter your full name.

"Username:" is your email username.

For "Mail Host:" enter your mail server name. If you are creating a profile for your leland account, your mailhost entry should be "username.pobox.stanford.edu", where username is your user account ID.

For the "Return address:" field enter the address recipients of your email will reply to when you send them email using this alternate personality. You should specify your primary email address in this field.

If you want to check mail from this second account regularly, enable the "Check for mail" option and enter the number of minutes between checks (entering a value less than 10 is not recommended).

You should instruct Eudora to "Leave mail on server" if you will be reading your email from this account on another computer (instructions for using Eudora to read your mail from two or more computers are here).

You can specify even more accounts for Eudora to check from by click the "New" button and entering alternate "Username", "Mail Host", and "Return address" information.

Click "OK" to finish your profile. Next time you check mail, Eudora will search both your default ("Dominant") account as well as any alternate accounts you specified.
