Mixminion

- Fixed a bug that crashed your server when another server's KeyID was
incorrect.
- Add minimal handlers for TERM and HUP signals.
- Add a disclaimer to main usage message.

- BUGFIX: A nasty bug is fixed that could, under just the right
circumstances, send the server into an infinite loop and fill up your
hard drive. If you're running a server, you *should* upgrade.
- Server log messages are more reasonably structured.
- setup.py is more clever about half-installed Python.
- "list-servers" now supports the same directory-download options as
does "send".

- A real SMTP exit module to relay messages via a local MTA. Blacklisting
is supported by address, by username, by host, by entire domain, and
by regular expression.
- Integrated directory support for clients.
- Automatic path selection, along with a better user interface to specify
paths.
- You can now enable Cottrell (DynamicPool) and Binomial Dynamic Pool
batching, though they are disabled by default to make the system more
testable.
- Servers resist certain trivial DoS attacks more strongly. In
particular, you should no longer be able to send zlib bombs or flood a
server with open connections.
- Clean build process under FreeBSD.
- Ability to run server as a daemon.
- Slightly better documentation and error messages.
- Better resistance to newline corruption of server descriptors.
- Other bugfixes and performance improvements too numerous to mention.

- You can run a rudimentary server that can deliver to other Mixminion
servers, that can use Mixmaster to deliver to any external address,
or that sends SMTP directly to a preconfigured set of addresses.
- You can send anonymous email via these servers.
