POP3 Proxy Mode vs Polling Mode - This is an important setting. If you choose POP3 Proxy Mode, then Spam Sleuth will act as your e-mail server after getting your e-mail and eliminating the spam. If you choose Polling Mode, then Spam Sleuth will analyze all of your e-mail, delete the spam from the server, and leave the good e-mail for your e-mail program to pick up.
Incoming Server (POP3) - This is the name or IP address of your e-mail server. You can get it from your e-mail program if you don't know it.
Username - This is the username for your e-mail account. It is usually the first part of your e-mail (before the @).
Password - This is the password for your e-mail account. You may leave this blank if you are using POP3 Proxy Mode. If you check for e-mail with your e-mail program, Spam Sleuth will get the password from the e-mail program. If you leave the password blank and you check manually with Spam Sleuth, you will be prompted for the password.
Check Every - This will determine how often Spam Sleuth checks for e-mail. If you are not using POP3 Proxy Mode, then make sure Spam Sleuth scans your e-mail before your e-mail program gets your e-mail. If you set it to 0, then it will only check when you check manually, or when your e-mail program checks for e-mail, provided that Last minute check is turned on.
