# mailwithtor
# -----------
# A simple socat script to start a local SOCKS4a server to connect msmtp and 
# Tor.
#
# Usage: 
#       $ ./mailwithtor & 
#       $ mutt
#
# Note: This uses Tor between you and your mailserver. This means:
#
#       A local passive observer will see that you're using Tor, and the email
#       recipient will see that the email came from your email account at your
#       mailserver.
#
#       If your mailserver is crappily configured, and include an
#       "X-Originating-IP" header or something similar, then this will hide
#       your IP from that.
#
#       Pretty much the only purpose of this script is to hide from passive
#       observers on your local network that you are connecting to a certain
#       mailserver.

## set this to your Tor SocksPort:
SOCKS_PORT=9050

## set these to the address and port of your mailserver:
MAILSERVER_FQDN="mailserver.com"
MAILSERVER_PORT=465

## YOU SHOULDN'T NEED TO CHANGE ANY OF THE FOLLOWING VARIABLES:
## The "Account" stanza in your msmtp config that you wish to use:
MSMTP_ACCOUNT="default"
LOG_FILE="${HOME}/.mailwithtor.log"
LOCK_FILE="${HOME}/.mailwithtor-lockfile"
## Port for socat to pipe incoming connections to its own SOCKS server:
SOCAT_LISTEN_PORT=2525

## If you're calling this from commandline before starting mutt, uncomment the
## following line and use "$ mailwithtor &":

sudo socat -d -d -d -lu -L ${LOCK_FILE} -lf ${LOG_FILE} TCP4-LISTEN:2525,fork SOCKS4A:localhost:$MAILSERVER_FQDN:$MAILSERVER_PORT,socksport=$SOCKS_PORT,socksuser=""

## If you're setting "set sendmail='/path/to/mailwithtor'", then 
## uncomment the following lines: 
## NOTE: this is broken. specifically the getting-the-passphrase-from-the-sudo-
## prompt part.
#sudo %?p?--passphrase-fd 0? socat -d -d -d -lu -L $HOME/.mailrc/$LOCK_FILE -lf $HOME/.mailrc/$LOG_FILE TCP4-LISTEN:2525,fork SOCKS4A:localhost:$MAILSERVER_FQDN:$MAILSERVER_PORT,socksport=$SOCKSPORT,socksuser="" & /usr/bin/msmtp -a $MSMTP_ACCOUNT
