This document covers configuration of the following POP clients that support connecting to a secure POP server:
- Mozilla / Thunderbird
- Netscape Messenger
- Microsoft Outlook
- Microsoft Outlook Express
- Fetchmail (linux)
Make sure you read the NOTE at the bottom of this page.
|POP (Incoming) Server:||pop.cs.princeton.edu|
|POP Settings / Port:||SSL / Port 995|
|SMTP (Outgoing) Server:||smtp.cs.princeton.edu|
|SMTP Settings / Port:||TLS (SSL) with Authentication / Port 587|
Make sure "Use secure connection (SSL)" is selected in the Server Settings section of the "Mail & Newsgroups Account Settings" dialog.
You should also turn on SSL and authentication in the "Outgoing Server (SMTP)" section, though in most cases this is not required. However, this is required if you will be sending mail from outside the department, including users of the department's dial-up service.
Make sure "This server requires a secure connection (SSL)" is checked in the Advanced tab of the mail server properties dialog.
You should also turn on authentication in the Servers tab, though in most cases this is not required. However, this is required if you will be sending mail from outside the department, including users of the department's dial-up service.
When specifying what POP server to connect to, it is imperative that you say "pop.cs.princeton.edu". (Not "mail.cs.princeton.edu", not "mail", and not "pop".) This is because when a client connects to the secure POP daemon, the certificate that is presented to it by the server identifies the server as "pop.cs.princeton.edu". If you connect to the secure POP server using a different alias, both Messenger and Outlook will complain that the certificate is not valid. This warning also applies to the SMTP server if you are using SSL/TLS. You must specify the name as "smtp.cs.princeton.edu".
