Entrenando a thunderbird

Los clientes de email hoy en día cuentan con filtros para bloquear spam. Thunderbird no es la excepción y cuenta con filtros gestionados por spamassassin. Estos filtros debemos irlos entrenando para que hagan bien su trabajo, marcando los spam en la medida que lleguen y no sean detectados y viceversa, desmarcando de spam los mails ham (mail benignos, no dañinos) llegando asi a tener una buena protección. Aunque una buena protección comienza desde el servidor de email nunca esta demás tener filtros también en el email client.

Configuracion:

-Activamos el filtro en  las opciones de cuentas (Account Settings)

-Si el mail llega y no es marcado y movido automaticamente por los filtros antispam, nos paramos encima del mail dandole click y despues damos click en el boton Junk (spam) con lo cual el mail sera movido a la carpeta Junk o la que hayamos configurado para almacenarlos.

-Si es a la inversa, un mail ham (benigno, no dañino) es marcado y movido a la carpeta Junk por error, vamos a la carpeta Junk, nos paramos encima del mail dandole click y damos click en el boton Not Junk (No spam)

Esto ultimo regresara el mail a la carpeta original y entrenara al spamassassin para que no vuelva a marcar este mail como spam. En la medida que entrenen los filtros, este sera mas exacto y se equivocara menos.

Filtrar mails con imagenes spam

Los spammers cada dia buscan formas nuevas de burlar nuestros filtros antispam y hacernos llegar molestos mails como los de Viagra. Ahora es comun que nos lleguen en formato grafico. Hoy instalaremos FuzzyOCR, un plugin que se agrega al spamassassin para poder parar estos mails.
Usaremos un server Centos 5.5 actualizado, con spamassassin.

-Comenzamos agregando el repositorio de dag.
Para un server i386:

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Para un server x86-64

rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

-Instalamos dependencias

yum install netpbm gifsicle giflib giflib-utils gocr ocrad ImageMagick tesseract perl-String-Approx perl-MLDBM perl-CPAN perl-MLDBM-Sync


-Descargamos la ultima version de fuzzyocr

wget -c http://users.own-hero.net/~decoder/fuzzyocr/fuzzyocr-3.6.0.tar.gz

-Descomprimimos

tar xzvf fuzzyocr-3.6.0.tar.gz

-Copiamos

cd FuzzyOcr-3.6.0
cp FuzzyOcr.cf FuzzyOcr.scansets FuzzyOcr.preps FuzzyOcr.words FuzzyOcr.pm  /etc/mail/spamassassin/

mkdir /etc/mail/spamassassin/FuzzyOcr
cp  FuzzyOcr/* /etc/mail/spamassassin/FuzzyOcr

-Configuramos

vi /etc/mail/spamassassin/FuzzyOcr.cf

focr_global_wordlist /etc/mail/spamassassin/FuzzyOcr.words
focr_bin_helper pnmnorm, pnminvert, pamthreshold, ppmtopgm, pamtopnm
focr_bin_helper tesseract
focr_path_bin /usr/local/netpbm/bin:/usr/local/bin:/usr/bin

focr_db_max_days 15

-Probamos este funcionando ok

Importar emails en formato mbox a thunderbird

Hoy se me presento el siguiente problema. Un usuario de webmail descargo todos sus mails en la carpeta Inbox a thunderbird 3 pero los mails en las demas carpetas, quedaron en el servidor. Despues de descargar los mbox al equipo local me sorprendo de que thunderbird bajo Linux en la opcion de Import solo permite hacerlo con Communicator 4.x.

Asi que hice lo siguiente.

Para este ejemplo usamos thunderbird 3.0.4 bajo linux, imagino que para Windows y Mac debe ser parecido en teoria.

Por ejemplo, tenemos 2 mbox:

contructora.mbox
familia.mbox

Las cuales queremos que queden en carpetas separadas bajo Local Folders.

-En Thunderbird creamos las carpetas constructora y familia bajo Local Folders

-Nos cambiamos en una consola al directorio Local Folders de Thunderbird, en mi caso es:

cd .mozilla-thunderbird/9pyl51td.default/Mail/Local\ Folders/

-Verificamos que esten creados los files de constructora y familia

ls -la
total 32984

-Borramos los files familia y constructora, dejando los msf

rm familia constructora

-Copiamos los mbox constructora y familia ahi dentro. Suponiendo que en nuestro home solo tenemos 2 mbox. OJO, terminamos con un punto .

cp ~/*.mbox .

-Cerramos Thunderbird y lo volvemos a abrir. Nos paramos en una de las carpetas, dependiendo de la cantidad y tamaño de los mails, demorara un poco para mostrar los mails. Al importarlos, todos aparecen como no leídos.
