Read the RFC that defines POP3 (RFC1939). You CANNOT download only specific header lines. CANNOT. There is no such command in the POP3 standard. These tools probably use POP3's TOP command to download the complete header, along with a specified number of lines of the body of the message (ie "TOP 2 1" to download the header and first line of message number 2).
Any tool that claims that it works without downloading the message should actually say that it downloads the header and tells the POP3 server what to do with it, and hides the process from you so that it APPEARS that no downloading has taken place.
This still limits you to filtering based on headers, which may or may not be good enough for your needs.
