Ruth:
Are you using Outlook? I usually get all the information I need by looking at the Account configuration in Outlook.

-"Mail Server" = Outlook "Outgoing mail server (SMTP)"
-"Display Name" = The name you want to show on the email (ie. Ruth - ABC Company)
-"Account Name" = Your email address
-"Password" = Your password to gain access to email
-"Port" = Outlook - click on "More settings" button then on the "Advanced" tab - Look for "Outgoing server (SMTP)"

The hard one is usually the password since many users no longer remember their password. The Outlook references are based on Outlook 2010. All of the same information is there in earlier versions; the fieldnames may be slightly different.
