Here you define settings for the local POP3-server you will be using in the future. Just remember your username and password settings, because you will also need them if you wish to change the settings in the future.
You can also set the port your server will be binding into. 110 is the default, but if you for some reason already have something running in port 110, you can set it to whatever you want. If you define the server into some port that is in use, the application warns you about this and refuses to start the local server.
On this page, there are a lot of other settings, too. Some of them are not too self-explanatory, but for most, the default settings should be just ok to use.
Clicking on the "Add"-button allows you to add a new POP3-account to retrieve messages from. You need to know the POP3-server's address, the port number (this is usually 110 - the standard POP3-port), your username and your password. This information is usually given to you by your ISP; I'm definetly not the person to ask them from - I simply can't know.
Clicking on the "Edit"-button allows you to change the currently selected account's information.
Clicking on the "Delete"-button removes the currently selected account. Of course, a "Are you certain"-dialog is implemented in case you click this button accidentally.
Whitelist is a list of eMail-addresses that are considered "clean". If a sender's eMail-address matches address on the list, it is not checked for spam, but rather passed through in any case. You can also use partial addresses in the list, so that for example any mail coming from a single domain can be marked as "clean". Whitelist overrides any checks - even the blacklist. If you're familiar with regexps, you can use them here - again with your own responsibility. It is not advised to do so.
Blacklist is a list of eMail-addresses that are considered "dirty". If a sender's eMail-address matches address on the list, it is not checked for spam, because there's no need. If it's dirty, it's dirty. Blacklisted addresses are always considered spam. As with the whitelist, you can use partial addresses in this list as well as regexps. It is not advised to use regexps, because you can do a lot of harm to yourself with them. It's so easy to shoot your own foot. And of course it must be remembered that if whitelist and blacklist both have same addresses, whitelist overrides blacklist.
If you use whitelist or blacklist, be sure to also check the "Enable personal *****list"-checkbox.
Settings on this page define what should be done to the different levels of spam as identified by PSFPOP3.
On this tab, you also have the possibility to change the subject line of the messages. If you have chosen to "delivered to mailbox"-option, you can use the changed subject line to send the different messages to some special folders in your mail client.
UIDL-command, so this setting just depends on your personal preference.
