If the mail server is listed in the spam database you queried, it will return an answer indicating that the mail server is listed.

LDAP - Lightweight Directory Access Protocol (LDAP) is a communication protocol for accessing online directory services. Programs like Outlook and Thunderbird use LDAP to retrieve contact lists from SmarterMail.

List Server - A list server (mailing list server) is a program, or a feature in a program, that handles subscription requests for a mailing list and distributes new messages, newsletters, or other postings from the list's members to the entire list of subscribers as they occur or are scheduled.

SMTP - Simple Mail Transfer Protocol is a TCP/IP (Internet) protocol used in sending and receiving email. However, since it's limited in its ability to queue messages at the receiving end, it's usually used with one of two other protocols, POP3 or IMAP, that let the user save messages in a server mailbox and download them periodically from the server. In other words, users typically use a program that uses SMTP for sending email and either POP3 or IMAP for receiving messages that have been received for them at their local server.
