+# BATCH STRESS TEST FOR IMAP ----------------------
+# http://imgs.xkcd.com/comics/science.jpg
+#
+# Run imaptest against a LEAP IMAP server
+# for a fixed period of time, and collect output.
+#
+# Author: Kali Kaneko
+# Date: 2014 01 26
+#
+# To run, you need to have `imaptest` in your path.
+# See:
+# http://www.imapwiki.org/ImapTest/Installation
+#
+# For the tests, I'm using a 10MB file sample that
+# can be downloaded from:
+# http://www.dovecot.org/tmp/dovecot-crlf
+#
+# Want to contribute to benchmarking?
+#
+# 1. Create a pristine account in a bitmask provider.
+#
+# 2. Launch your bitmask client, with different flags
+# if you desire.
+#
+# For example to try the nosync flag in sqlite:
+#
+# LEAP_SQLITE_NOSYNC=1 bitmask --debug -N --offline -l /tmp/leap.log
+#
+# 3. Run at several points in time (ie: just after
+# launching the bitmask client. one minute after,
+# ten minutes after)
+#
+# mkdir data
+# cd data
+# ../leap_tests_imap.zsh | tee sqlite_nosync_run2.log
+#
+# 4. Submit your results to: kali at leap dot se
+# together with the logs of the bitmask run.
+#
+# Please provide also details about your system, and
+# the type of hard disk setup you are running against.
+#

+# the user and mbox as parameters. Like me.

+ (4) Optional parameters: none
+ (5) Security considerations: Must be treated as opaque while in

+
+ The multipart/signed content type contains exactly two body parts.
+ The first body part is the body part over which the digital signature

+ contains the control information necessary to verify the digital
+ signature. The first body part may contain any valid MIME content
+ type, labeled accordingly. The second body part is labeled according

+
+ When the OpenPGP digital signature is generated:
+
+ (1) The data to be signed MUST first be converted to its content-
+ type specific canonical form. For text/plain, this means
+ conversion to an appropriate character set and conversion of
+ line endings to the canonical <CR><LF> sequence.
+
+ (2) An appropriate Content-Transfer-Encoding is then applied; see
+ section 3. In particular, line endings in the encoded data
+ MUST use the canonical <CR><LF> sequence where appropriate
+ (note that the canonical line ending may or may not be present
+ on the last line of encoded data and MUST NOT be included in
+ the signature if absent).
+
+ (3) MIME content headers are then added to the body, each ending
+ with the canonical <CR><LF> sequence.
+
+ (4) As described in section 3 of this document, any trailing
+ whitespace MUST then be removed from the signed material.
+
+ (5) As described in [2], the digital signature MUST be calculated
+ over both the data to be signed and its set of content headers.

+Leap SMTP Gateway
+=================
+
+The Bitmask Client runs a thin SMTP gateway on the user's device, which
+intends to encrypt and sign outgoing messages to achieve point to point
+encryption.
+
+The gateway is bound to localhost and the user's MUA should be configured to
+send messages to it. After doing its thing, the gateway will relay the
+messages to the remote SMTP server.
+
+Outgoing mail workflow:
+
+ * SMTP gateway receives a message from the MUA.
+
+ * SMTP gateway queries Key Manager for the user's private key.
+
+ * For each recipient (including addresses in "To", "Cc" anc "Bcc" fields),
+ the following happens:
+
+ - The recipient's address is validated against RFC2822.
+
+ - An attempt is made to fetch the recipient's public PGP key.
+
+ - If key is not found:
+
+ - If the gateway is configured to only send encrypted messages the
+ recipient is rejected.
+
+ - Otherwise, the message is signed and sent as plain text.
+
+ - If the key is found, the message is encrypted to the recipient and
+ signed with the sender's private PGP key.
+
+ * Finally, one message for each recipient is gatewayed to provider's SMTP
+ server.
+
+
+Running tests
+-------------
+
+Tests are run using Twisted's Trial API, like this::
+
+ python setup.py test -s leap.mail.gateway.tests
