This seems to fix the security problem with '\0' in domain names which
was also present in openssl and nss. (CVE-2010-1192)
(The bundled changelog does only beat around the bush.)
* lib/Mail/DKIM/DkSignature.pm, Signature.pm: avoid calling lc() on
an undefined value (this generates warnings in Perl 5.12.x).
* lib/Mail/DKIM/PrivateKey.pm (load): fix bug where a private key file
named '0' could not be loaded
* lib/Mail/DKIM/DkSignature.pm (new): accept Key parameter when
constructing a DomainKey signature object
* t/external_signer.t: test use of an alternate object for Key
during a "sign" operation
* lib/Mail/DKIM/Signer.pm: document use of an alternate object for
PrivateKey objects
* lib/Mail/DKIM/Signer.pm: import PrivateKey.pm in this module,
rather than in the Algorithm modules
* lib/Mail/DKIM/PrivateKey.pm: document the sign_digest() method
* lib/Mail/DKIM/Algorithm/*: use sign_digest() rather than
sign_sha1_digest()
* t/public_key.t: test that DNS failure reason is given, when
DNS returns no results
* lib/Mail/DKIM/DNS.pm: bugfix (introduced by async_dns branch):
preserve $@ in case of no error
* lib/Mail/DKIM/{DNS,Signature,PublicKey,Policy}.pm: merged my
"async dns" branch
* lib/Mail/DKIM/Policy.pm: new fetch_async method, seems to work
* lib/Mail/DKIM/Signature.pm: new fetch_public_key method,
which starts an asynchronous query for the public key
referenced by this signature; redesign get_public_key to
know how to complete the query
* lib/Mail/DKIM/PublicKey.pm: new fetch_async method: starts a
query and returns a subref that when called will complete the
query
* lib/Mail/DKIM/DNS.pm: new query_async method: starts a query and
returns a subref that when called will complete the query
* MANIFEST: include sample_mime_lite.pl script in tarball

Mail) sender authentication system proposed by the E-mail Signing Technology
Group (ESTG), now standardized by the IETF (RFC4871). It also includes
implementations of the Author Domain Signing Practises (ADSP, RFC5617) and
Vouch By Reference (VBR, RFC5518) proposed standards.
The project started from a code fork of version 2.8.3 of the open source
dkim-milter package developed and maintained by Sendmail, Inc.

Changelog for Dovecot 1.2.15:
* acl: Fixed the logic of merging multiple ACL entries. Now it works as
documented, while previously it could have done slightly different
things depending on the order of the entries.
For details see http://www.dovecot.org/list/dovecot/2010-October/053452.html
* acl: Don't give admin rights to all owner mailboxes. This was
originally done to make sure that mailbox owner couldn't accidentally
remove their own admin rights. But this is already prevented by
SETACL command, so it's not necessary. Also sysadmin may have
intentionally removed some admin rights from some mailboxes
(especially when using symlinked shared mailboxes).
- Maildir: Fixed potential "Duplicate file entry" in dovecot-uidlist
file errors.
- Maildir: Avoid unnecessary uidlist recreation during mail delivery.
- imap: When SELECT fails, it didn't close the previous mailbox.
- Dovecot master process could have died if it got SIGCHLD signals
very rapidly while it was trying to log. This could have happened
for example if a lot of imap/pop3 sessions disconnected at the exact
same time.
Changelog for Sieve 0.1.18:
- Imap4flags: fixed segfault bug occuring in multiscript context.
Occured in specific situations when a script using imap4flags was
followed in the sequence by scripts not using imap4flags.
- Imap4flags: fixed bug in setflag command; when parameter was a
stringlist, only the last item was actually set.
- Prevented assertion failure due to currupt binary string
representation. If the string were missing a final \0 character an
assertion was produced in stead of a binary corruption error.
- Multiscript: fixed duplicate implicit keep caused by erroneous
execution state update.
- Fixed Sieve script name checking to properly handle length limit
and added 0x00ff as invalid character.
- Removed spurious old stdio.h (top) includes; these caused compile
issues on specific systems.
- Fixed default Sieve capability (as reported by ManageSieve): extra
extensions spamtest, spamtestplus and virustest were enabled by
default. These should, however, only be enabled when properly
configured and there is no default configuration.
- Variables extension: fixed :length set modifier to recognize utf8
characters in stead of octets.
- Fixed unnecessary reporting of dummy extensions in ManageSieve
SIEVE capability; the comparator-i;octet and
comparator-i;ascii-numeric 'extensions' were reported explicitly.
- LDA Sieve plugin: added _version symbol to enable Dovecot's plugin
version check. Without this check, people can forget to recompile
the plugin, which can lead to unexpected effects.
Changelog for ManageSieve 0.11.12:
- Fixed error handling of PUTSCRIPT commmand; save commit errors
would not make the command fail.
- Fixed PUTSCRIPT bug causing it to hang when given an empty script
name.

Changelog:
1.5.4: 2010-09-13 23:59 UTC
Critical Security release.
It is highly recommended that users of 1.5.3 upgrade to this release, a change in the boundary detection
code introduced a potential denial of service attack.
Bug Fixes
#17862 - quote boundary preg_split code
1.5.3: 2010-09-05 09:26 UTC
Major Bugfix release.
Apart from a major cleanout of the bug tracker for this package, this
release includes a revamped parseHeaderValue which removes the rather
flakey regex, with a real parser, which should be considerably more
robust.
Bug Fixes
#17844 - all regression tests fixed - remove the last of the while
list each() .. this is 2010 ;)...
#11410 - support wap multipart
#9616 - long strings as filename
etc.. aaa*0=.... aaa*1=.... aaa*2=.... (merged into aaa=.....)
#9100 - change to preg_split for mime boundary detection , in theory
should catch boundaries in nested situations better...
#7709 - check for last element on boundary split to see if its usable
#7065 - wrapped header lines with encoding should be concated without spaces
#6495 - missing body in decoded object
#11537 - better decode and multi-line support
1.5.2: 2010-09-02 12:01 UTC
Bug Fixes
#4739 - regexp parsing of header values does not balance quoting
correctly - Fix sponsored by http://webyog.com#17325 - empty body messages are valid messages
#17276 - remove &new usage which throws errors now

When the SSL layer buffers data, select() does not return
true, hence, is not indicating that pending data. It seems
that select() queries the TCP stack only.

the block size of Net::SSLeay at the current time of 32KB.

Action Mailer is a framework for designing email-service layers. These layers
are used to consolidate code for sending out forgotten passwords, welcome
wishes on signup, invoices for billing, and any other use case that requires
a written notification to either a person or another system.
Action Mailer is in essence a wrapper around Action Controller and the
Mail gem. It provides a way to make emails using templates in the same
way that Action Controller renders views using templates.
Additionally, an Action Mailer class can be used to process incoming email,
such as allowing a weblog to accept new posts from an email (which could even
have been sent from a phone).
(This is part of Ruby on Rails 3.)
Mail is an internet library for Ruby that is designed to handle emails
generation, parsing and sending in a simple, rubyesque manner.
The purpose of this library is to provide a single point of access to handle
all email functions, including sending and receiving emails. All network
type actions are done through proxy methods to Net::SMTP, Net::POP3 etc.
Built from my experience with TMail, it is designed to be a pure ruby
implementation that makes generating, sending and parsing emails a no
brainer.
It is also designed form the ground up to work with Ruby 1.9. This is because
Ruby 1.9 handles text encodings much more magically than Ruby 1.8.x and so
these features have been taken full advantage of in this library allowing
Mail to handle a lot more messages more cleanly than TMail. Mail does run on
Ruby 1.8.x... it's just not as fun to code.
Finally, Mail has been designed with a very simple object oriented system
that really opens up the email messages you are parsing, if you know what
you are doing, you can fiddle with every last bit of your email directly.
* Use lang/ruby/gem.mk instead of misc/rubygems/rubygem.mk.
* Add LICENSE.
* Remove default value of GEM_BUILD.
=== 1.2.7.1 / 2010-02-07
* Fixed stray ruby-debug
* Re indented RChardet, and handled old syntax
* Add LICENSE.
* Remove default value of GEM_BUILD.
== MIME::Types 1.16
* Made compatible with Ruby 1.8.6, 1.8.7, and 1.9.1.
* Switched to the 'hoe' gem system and added a lot of build-time tools.
* Updated the MIME types to the list based on the values in the Perl library
version 1.27. Also updated based on external source information and bug
reports.
