Please NOTE:

When specifying a server to connect to, it is imperative that you use "webmail.cs.princeton.edu". (Not "mail.cs.princeton.edu", not "mail", and not "webmail".) This is because when a client connects to the server over SSL, the certificate that is presented by the server identifies the server as "webmail.cs.princeton.edu". If you connect to the server using a different alias, your client will complain that the certificate is not valid.
