For outgoing emails to work you need to make sure the php.ini is configured correctly for outgoing mail.
SMTP = myserver.localnet.com
sendmail_from = me@localhost.com
The POP3 fetch requires that you set up a scheduled task pointing to the cron.php file.
path\to\php.exe "path\to\cron.php"
This must be setup to run every few minutes. (mine runs every minute)
