Some specific portions of INN are covered by different licenses, usually
more permissive ones.  Those licenses, if present, will be noted
prominantly at the top of those source files.  Specifically (but possibly
not comprehensively):

   authprogs/pwcheck.c may only be used for non-commercial purposes and by
   Internet Service Providers and other entities for internal purposes.
   See the beginning of the file for full details.

   backends/pgpverify.in and frontends/signcontrol.in are under a license
   very similar to the above but with UUNET Technologies, Inc. as the
   copyright holder.  See the end of those files for details.

   backends/shrinkfile.c, frontends/scanspool.in, lib/concat.c,
   lib/endian.c, and lib/parsedate.y are in the public domain.

   lib/inet_aton.c, lib/inet_ntoa.c, lib/memchr.c, lib/memcmp.c,
   lib/memmove.c, lib/memset.c, lib/strcasecmp.c, lib/strspn.c, and
   lib/strtok.c are taken from BSD sources and are covered by the standard
   BSD license.  See those files for more details.

   lib/md5.c is covered under the standard free MD5 license from RSA Data
   Security.  See the file for more details.
