NAME
Lamson - Lamson is a modern Pythonic mail server built like a web
application server.
SYNOPSIS
lamson <action> [options]
DESCRIPTION
lamson is a pure Python SMTP server designed to create robust and
complex mail applications in the style of modern web frameworks such as
Django. Unlike traditional SMTP servers like Postfix or Sendmail,
Lamson has all the features of a web application stack (ORM, templates,
routing, handlers, state machines, Python) without needing to configure
alias files, run newaliases, or juggle tons of tiny fragile processes.
Lamson also plays well with other web frameworks and Python libraries.
ACTIONS
log [-port PORT] [-host HOST] [-pid PIDFILE] [-chroot True|False]
[-chdir DIR] [-umask UMASK] [-uid UID] [-gid GID] [-FORCE True|False]
Runs a logging only server on the given hosts and port. It logs
each message it receives and also stores it to the run/queue so
that you can make sure it was received in testing.
lamson log -port 8825 -host 127.0.0.1 \
-pid ./run/log.pid -chroot False \
-chdir "." -umask False -uid False -gid False \
-FORCE False
If you specify a uid/gid then this means you want to first
change to root, set everything up, and then drop to that UID/GID
combination. This is typically so you can bind to port 25 and
then become "safe" to continue operating as a non-root user.
If you give one or the other, this it will just change to that
uid or gid without doing the priv drop operation.
send [-port PORT] [-host HOST] [-debug 0|1] [-sender EMAIL] [-to EMAIL]
[-subject SUBJECT] [-body BODY] [-attach FILENAME]
Sends an email to someone as a test message. See the sendmail
command for a sendmail replacement.
lamson send -port 8825 -host 127.0.0.1 -debug 1 \
-sender EMAIL -to EMAIL -subject STR -body STR
-attach False’
sendmail [-port PORT] [-host HOST] [-debug 0|1] -- [RECIPIENTS]
Used as a testing sendmail replacement for use in programs like
mutt as an MTA. It reads the email to send on the stdin and
then delivers it based on the port and host settings.
lamson sendmail -port 8825 -host 127.0.0.1 -debug 0 --
[recipients]
start [-pid PIDFILE] [-FORCE True|False] [-chroot True|False] [-chdir
DIR] [-umask UMASK] [-uid UID] [-gid GID] [-boot BOOTMODULE]
Runs a lamson server out of the given directory.
lamson start -pid ./run/smtp.pid -FORCE False -chroot False
-chdir "." \
-umask False -uid False -gid False -boot config.boot
stop [-pid PIDFILE] [-KILL True|False] [-ALL DIR]
Stops a running lamson server. Give -KILL True to have it
stopped violently. The PID file is removed after the signal is
sent. Give -ALL the name of a run directory and it will stop
all pid files it finds there.
lamson stop -pid ./run/smtp.pid -KILL False -ALL False
restart [-pid PIDFILE] [-FORCE True|False] [-chroot True|False] [-chdir
DIR] [-umask UMASK] [-uid UID] [-gid GID] [-boot CONFIG] [-KILL
True|False] [-ALL DIR]
Simply attempts a stop and then a start command. All options
for both apply to restart.
status [-pid PIDFILE]
Prints out status information about lamson useful for finding
out if it’s running and where.
lamson status -pid ./run/smtp.pid
queue [-pop|-get|-remove|-count|-clear|-keys] [-name QUEUE]
Let’s you do most of the operations available to a queue.
lamson queue (-pop | -get | -remove | -count | -clear | -keys)
-name run/queue
routes [-path PATH] -- [CONFIG] [-test EMAIL]
Prints out valuable information about an application’s routing
configuration after everything is loaded and ready to go. Helps
debug problems with messages not getting to your handlers. Path
has the search paths you want separated by a ’:’ character, and
it’s added to the sys.path.
lamson routes -path $PWD -- config.testing -test ""
It defaults to running your config.testing to load the routes.
If you want it to run the config.boot then give that instead:
lamson routes -- config.boot
You can also test a potential target by doing -test EMAIL.
gen [-project NAME]
Generates various useful things for you to get you started.
lamson gen -project STR
spell [-language LANG] -- [FILES]
Runs the PyEnchant spell checker on the given file. Use this to
train the spell checker for unit test runs when new words show
up.
lamson spell -langauge en_US -- [files]
It will run interactively and if you perform an edit on the file
it will save your changes back to the file and make a backup
named with .bak.
web [-basedir DIR] [-port PORT] [-host HOST]
Starts a very simple files only web server for easy testing of
applications that need to make some HTML files as the result of
their operation. If you need more than this then use a real web
server.
lamson web -basedir "." -port 8888 -host ’127.0.0.1’
This command doesn’t exit so you can view the logs it prints
out.
cleanse [-input MAILBOX] [-output MAILBOX]
Uses Lamson mail cleansing and canonicalization system to take
an input maildir (or mbox) and replicate the email over into
another maildir. It’s used mostly for testing and cleaning.
blast [-input MAILBOX] [-port PORT] [-host HOST] [-debug 0|1]
Given a maildir, this command will go through each email and
blast it at your server. It does nothing to the message, so it
will be real messages hitting your server, not cleansed ones.
version
Prints the version of Lamson, the reporitory revision, and the
file it came from.
help [-for CMD]
Prints out help for the commands.
lamson help
You can get help for one command with:
lamson help -for STR
