Stage 5: Specify Internet mail servers, domain, and news server
These settings are available because you downloaded Outlook Express. You can provide this information, so your users will only have to provide one account name and password, or you can leave these settings blank.
Incoming mail (POP 3) server
The Post Office Protocol version 3 (POP3) is a protocol that permits a workstation to dynamically access a mail drop on a server in a useful fashion. The address should include the server name, domain name, and subdomain; an example is pop01.microsoft.com.
Outgoing mail (SMTP) server
An SMTP server is the outgoing mail server. In some cases, the SMTP server may have the same name as your POP3 server.
Internet news server
A Network News Transfer Protocol (NNTP) is the protocol used to distribute network news messages to NNTP servers and to NNTP clients (news readers) on the Internet. NNTP provides for the distribution, inquiry, retrieval, and posting of news articles by using a reliable stream-based transmission of news on the Internet. An example server name is: microsoft.public.internetexplorer.ieak.
Default client
If you want Outlook Express to run when users click Mail or News on the Go menu in Internet Explorer and other components, select the Make Outlook Express the default mail client or Make Outlook Express the default news client check boxes.
Secure Password Authentication
You can use Secure Password Authentication (SPA) to authenticate your users' logons by selecting the Use Secure Password Authentication check box.
