Head to the web interface's Security tab, and enter the server name and port of your Secure Password Authentication-protected server. Once done, you simply need to change the server name in your mail program to 127.0.0.1 - you don't need to change the username.

Unfortunately, you can currently only have one SPA account through each installation of POPFile.

You have to start popfile with the following command (type it in exactly)

perl popfile.pl --set pop3_port=110 pop3_secure_server=pop3.email.msn.com pop3_secure_port=110

On your accounts, server page, make sure you have the following information:

Incoming mail server: 127.0.0.1
Account name: YOUR_MSN_ACCOUNT_NAME_ONLY 

Make sure that “Log on using Secure Password Authentication” is CHECKED. On the Advanced tab, make sure that “Incoming mail (POP3)” is set to 110 and that “This server requires a secure connection (SSL)” is UNCHECKED.

You should be able to check your mail now by clicking on the account name from your drop-down list.
