Externaliser la gestion des filtres de Gmail via imapfilter

Posted on 2017-04-26 by

Les labels sous Gmail et les filtres associés sont assez limités; il est impossible d’appliquer 2 labels en même temps et tous les filtres sont appliqués les uns après les autres, ce qui peut donner des résultats assez surprenants.

Afin de palier à ces limites, la gestion de mes filtres est assurée par imapfilter installé sur un serveur externe.

Installation du package

sudo apt-get install imapfilter
mkdir ~/.imapfilter
touch ~/.imapfilter/config.lua
echo "GMAIL PWD" > ~/.imapfilter/.password.offlineimaprc
chmod 600 ~/.imapfilter/.password.offlineimaprc

sudo apt-get install imapfilter

mkdir ~/.imapfilter

touch ~/.imapfilter/config.lua

echo "GMAIL PWD" > ~/.imapfilter/.password.offlineimaprc

chmod 600 ~/.imapfilter/.password.offlineimaprc

Configuration de imapfilter

function main()
 -- more timeout
 options.timeout = 120
 -- label can be created
 options.create = true
 -- authorize subscription
 options.subscribe = true
 -- ignore SSL certificates issue
 options.certificates = false
 
 -- Gmail account
 local home = IMAP {
 server = 'imap.gmail.com',
 username = '<EMAIL ADDRESS>',
 password = get_imap_password(".imapfilter/.password.offlineimaprc"),
 ssl = 'ssl3',
 }
 
 -- filter by subject
 move_subject(home, "INBOX", "NEWSLETTER", "Newsletter")
 
 -- filter by sender
 move_sender(home, "INBOX", "FACEBOOK", "@facebookmail.com")
 
end

function move_subject(imap, from, to, pattern)
 local messages = imap[from]:contain_subject(pattern)
 messages:move_messages(imap[to])
 end

function move_sender(imap, from, to, pattern)
 local messages = imap[from]:contain_from(pattern)
 messages:move_messages(imap[to]) 
 end
 
function get_imap_password(file)
 local home = os.getenv("HOME")
 local file = home .. "/" .. file
 local str = io.open(file):read()
 return str;
end

-- start imapfilter as daemon and run check every 3 seconds
become_daemon(3, main)

function main()

-- more timeout

options.timeout = 120

-- label can be created

options.create = true

-- authorize subscription

options.subscribe = true

-- ignore SSL certificates issue

options.certificates = false

-- Gmail account

local home = IMAP {

server = 'imap.gmail.com',

username = '<EMAIL ADDRESS>',

password = get_imap_password(".imapfilter/.password.offlineimaprc"),

ssl = 'ssl3',

}

-- filter by subject

move_subject(home, "INBOX", "NEWSLETTER", "Newsletter")

-- filter by sender

move_sender(home, "INBOX", "FACEBOOK", "@facebookmail.com")

end

function move_subject(imap, from, to, pattern)

local messages = imap[from]:contain_subject(pattern)

messages:move_messages(imap[to])

end

function move_sender(imap, from, to, pattern)

local messages = imap[from]:contain_from(pattern)

messages:move_messages(imap[to])

end

function get_imap_password(file)

local home = os.getenv("HOME")

local file = home .. "/" .. file

local str = io.open(file):read()

return str;

end

-- start imapfilter as daemon and run check every 3 seconds

become_daemon(3, main)

Lancement au démarrage

Création du script/etc/init.d/imapfilter via son éditeur préféré

sudo nano /etc/init.d/imapfilter
#!/bin/sh
#/etc/init.d/imapfilter

PID=`ps -elf | grep '/usr/bin/imapfilter' | grep -v grep | awk '{print $4}'`

# The following part carries out specific functions depending on arguments.
case "$1" in
 start)
 echo "Starting imapfilter"
 su - YOUR_USER -c '/usr/bin/imapfilter -c ~/.imapfilter/config.lua'
 ;;
 stop)
 echo "Stopping imapfilter"
 kill -9 $PID
 ;;
 *)
 echo "Usage: /etc/init.d/imapfilter {start|stop}"
 exit 1
 ;;
esac

exit 0

sudo nano /etc/init.d/imapfilter

#!/bin/sh
