Does PC-cillin 2002 automatically change a user's mail account?

Yes the account name and the name of the incoming POP3 mail server changes. However, if you are using a supported Internet mail client, like Outlook 98 or above, Outlook Express, Netscape Messenger, or Eudora, PC-cillin will automatically make these changes and will not affect you receiving mail.

If you are using an unsupported Internet mail client, modify the mail configuration settings (refer to the documentation of your mail client) by manually changing the incoming server to localhost and changing the account name to name/pop3server (where name is your account name and pop3server is the name of your POP3 mail server).
