 The Sendmail Mail Filter API (Milter) is designed to allow third-party
 programs access to mail messages as they are being processed in order
 to filter meta-information (headers) and content.
 .
 The Debian Sendmail package is built to support libmilter.
 .
 This is the libmilter static library and include files for development.
