Log Message:
fetchmail: update to 6.3.26

* add licenses
* remove kerberos conditional pre-configure rule (fixed in upstream)

Changes:
fetchmail-6.3.26 (released 2013-04-23, 26180 LoC):

# NOTE THAT FETCHMAIL IS NO LONGER PUBLISHED THROUGH IBIBLIO.
* They have stopped accepting submissions and consider themselves an archive.

# CRITICAL BUG FIX for setups using "mimedecode":
* The mimedecode feature failed to ship the last line of the body if it was
encoded as quoted-printable and had a MIME soft line break in the very last
line. Reported by Lars Hecking in June 2011.

Bug introduced on 1998-03-20 when the mimedecode support was added by ESR
before release 4.4.1 through code contributed by Henrik Storner.
Workaround for older releases: do not use mimedecode feature.

Earlier versions of this NEWS file claimed this bug fixed in fetchmail-6.3.23,
but it was not.

Fixes Launchpad Bug#1171818.

fetchmail-6.3.25 (released 2013-03-18, 26149 LoC):

# NOTE THAT FETCHMAIL IS NO LONGER PUBLISHED THROUGH IBIBLIO.
* They have stopped accepting submissions and consider themselves an archive.

# BUG FIXES
* Fix a memory leak in out-of-memory error condition while handling plugins.
  Report and patch by John Beck (found with Parfait static code analyzer).
* Fix a NULL pointer dereference in out-of-memory error condition while handling
  plugins.
  Report and patch by John Beck (found with Parfait static code analyzer).

# CHANGES
* Improved reporting when SSL/TLS X.509 certificate validation has failed,
  working around a not-so-recent swapping of two OpenSSL error codes, and
  a practical impossibility to distinguish broken certification chains from
  missing trust anchors (root certificates).
* OpenSSL decoded errors are now reported through report(), rather than dumped
  to stderr, so that they should show up in logfiles and/or syslog.
* The fetchmail manual page no longer claims that MD5 were the default OpenSSL
  hash format (for use with --sslfingerprint). Reported by Jakob Wilk,
  PARTIAL fix for Debian Bug#700266.
* The fetchmail manual page now refers the user to --softbounce from the
  SMTP/ESMTP ERROR HANDLING section.  Reported by Anton Shterenlikht.

# WORKAROUNDS
* Older systems that provide the older RFC-2553 implementation of getaddrinfo,
  rather than the current RFC-3493, and systems that do not provide this
  getaddrinfo() interface at all and thus use the replacement functions from
  libesmtp/getaddrinfo.?, might return EAI_NODATA when a host is registered in
  DNS as MX or similar, but without A or AAAA records.  Handle this situation
  when checking for multidrop aliases and treat EAI_NODATA the same as
  EAI_NONAME, i. e. name cannot be resolved.

  The proper fix, however, is to upgrade the operating system.
