Use APOP Authentication Some POP3 servers require encrypted Authenticated POP. If your ISP's server requires APOP, then check this setting.
Port The default port for POP3 is port 110. This is the port Spam Sleuth will use to go get e-mail. Do not confuse this port with the Listen port which is configured in Miscellaneous. Only change this setting if you have a specific reason that Spam Sleuth needs to communicate with an e-mail server on a different port.
Use SMTP Authentication - If your ISP requires authentication to send mail (not common), then check this box. If the username/password is the same as your POP3, then you can leave the SMTP Username/Password blank, and the program will use your POP3 Username/Password.
Outgoing Server (SMTP) Username/Password: - If your ISP requires a username and password to send e-mail (most don't) then you'll need to set that information here.
