.SH DESCRIPTION
-A parameter set to 1 tells the library to just list the names of files in a
-directory, instead of doing a full directory listing that would include file
-sizes, dates etc. This works for FTP and SFTP URLs.
+For FTP and SFTP based URLs a parameter set to 1 tells the library to list the
+names of files in a directory, rather than performing a full directory listing
+that would normally include file sizes, dates etc.
-This causes an FTP NLST command to be sent on an FTP server. Beware that some
-FTP servers list only files in their response to NLST; they might not include
-subdirectories and symbolic links.
+For POP3 a parameter of 1 tells the library to list the email message or
+messages on the POP3 server. This can be used to change the default behaviour
+of libcurl, when combined with a URL that contains a message ID, to perform a
+"scan listing" which can then be used to determine the size of an email.
+
+Note: For FTP this causes a NLST command to be sent to the FTP server. Beware
+that some FTP servers list only files in their response to NLST; they might not
+include subdirectories and symbolic links.
Setting this option to 1 also implies a directory listing even if the URL
doesn't end with a slash, which otherwise is necessary.
