bonjour,

je gère 2 mailing-lists hébergées chez free (http://ml.free.fr) et je souffre d'innombrables spams...

En effet en tant que modérateur, je reçois tous les mails d'erreurs et notamment :
- les tentatives d'envoi de messages sur la liste depuis des mails hors listes
- les envois de requête depuis des emails inexistants (cf ex ci-dessous)

By Jeremy Blackman, JT Traub and Ryan T. Dean

TO GET A LIST OF LISTS:
Send a message to the listar account on the server with a subject
of "lists".  A list of lists hosted by the server will be returned
to you.

TO SUBSCRIBE TO A LIST:

Send a message to the listar account on the server (you can just
reply to this message).  In the subject field, enter "subscribe
[listname]".  Or, you can send a message to "[listname]-request"
with a subject of "subscribe".

TO UNSUBSCRIBE FROM A LIST:
Send a message to the listar account on the server (you can just
reply to this message).  Enter "unsubscribe [listname]" in the
subject field.  You can also send a message to
"[listname]-request" with a subject of "unsubscribe".
        While you should NOT send your unsubscribe command to the list
        itself, Listar will attempt to trap such erroneous postings and
        forward them to the list administrators for proper handling.

TO GET A DIGEST EVERY DAY:
Send a message to the listar account on the server with a subject
of "set [listname] digest".  This will turn on digests, and you
will receive a digest however often the server is configured to
send them.

TO STOP GETTING A DIGEST:
Send a message to the listar account on the server with a subject
of "unset [listname] digest".  This will turn off digest mode, and
instead you will receive an eMail every time something is posted
to the list.

TO GET A DIGEST AND NORMAL POSTS:
Send a message to the listar account on the server with a subject
of "set [listname] digest2".  This will activate digest mode with
normal posting.  As each message is posted to the list it will be
sent to you, and you will receive a digest as well.  This flag
should be used INSTEAD of digest, NOT IN ADDITION TO.
To stop receiving digests in addition to normal posts, send a
message to the listar account with a subject of "unset [listname]
        digest2".  You will go back to receiving normal posts.

TO FIND OUT WHO IS ON A LIST:
Send a message to the listar account on the server with a subject
of "who [listname]".  You will receive a list of people subscribed
to the list who are not hidden.  Admins will be able to see
everbody, including those hidden.

TO HIDE ON A LIST:
Send a message to the listar account on the server with a subject
of "set [listname] hidden".  You will no longer appear on WHO
queries to the listserver.  No one (except Admins) will know you
are subscribed to the list unless you post to it (in which case
those people on the list will know you posted if nothing else).

TO STOP HIDING ON A LIST:
Send a message to the listar account on the server with a subject of
"unset [listname] hidden".  You will then show up on WHO queries
to the listserver.

TO GO ON VACATION:
Send a message to the listar account on the server with a subject of
"set [listname] vacation".  You will remain subscribed to the list
but will not receive any eMail as long as this flag is set.  To
come back from vacation, eMail the listar account with a subject of
        "unset [listname] vacation".

TO CHECK ON YOUR OWN STATUS:
Send a message to the listar account on the server with a subject
of "stats [listname]".  You will get a list of all the flags
currently set on your account.

TO GET A LIST OF FLAGS AVAILABLE:
Send a message to the listar account on the server with a subject
of "flags".  An eMail will be sent to you with the available flags
that you can set on your account.

TO GET A LIST OF COMMANDS AVAILABLE:
Send a message to the listar account on the server with a subject
of "commands".  An eMail will be sent to you with all the commands
that the server and any installed modules offer.

Gestionnaire de liste Listar/0.42 - fin de traitement/job execution complete.c'est plus que dérangeant (environ 40 spams par jour).
Je suppose que chaque administrateur de listes ml.free.fr a ce problème-là. Existe-t-il une solution ?

Bonjour,

Pour ma part j'en ai reçu jusqu'à une bonne centaine par jours :rolleyes:
1- Filtrer via l'interface du compte de messagerie
2- Utiliser Spamassassin qui va mettre en place un 2ème niveau de filtage
3- Thunderbird possède un autre système de détection de spams et est un bon complément à Spamassassin

[th0mas]

ah je savais pas qu'on pouvait incorporer spamassassin à thunderbird, bonne nouvelle !

1- ok depuis qqs temps déjà

2- j'ai juste installé le package "spamassassin", je suppose que ça fait pas grand chose tout seul ?

3- dans la partie "junk mail control", j'ai coché "trust junk mails set by" > "spamassassin" (et "move incoming messages...")

est-ce que ça suffit comme configuration ?
dans le header des messages entrant, y'a rien concernant spamassassin (avec les scores obtenus etc...), c'est normal ?

[nickole]

Alors là ...ce n'est pas moi qui l'avais installé (en plus sous Linux) ni paramétré mais voir par exemple :
http://wiki.apache.org/spamassassin/AideD'Installation
http://worldserver3.oleane.com/bouynot/gabuzomeu/alex/doc/spamassassin
http://artisan.karma-lab.net/connecter-spamassassin-a-postfix

J'ai le même souci, je recois plus de 40 mails de ce type tous les jours, c'est lourd
Et il n'y a rien d'autres à faire? On ne peut pas "empecher" de ce faire spammer comme ca?

[nickole]

Avec un bon filtrage et la phase d'apprentissage de reconnaissance des mails indésirables, ensuite en principe ils sont soit bloqués ou supprimés (filtrage au niveau du compte Free) soit déroutés directement vers un dossier de spams ou d'indésirables.

[th0mas]

en effet, après qqs jours d'apprentissage, j'avoue que le traitement des messages indésirables sous Thunderbird marche plutôt bien. J'ai pas encore été jusqu'à installer spamassassin sur ma machine (en local).

J'ai tout de même reçu sur 2 comptes spammés 1160 messages classés "Junk" depuis le 16 octobre, ça fait une bonne moyenne par jour ça !

[djnasty]

Moi ca part direct dans le dossier courrier indésirable de outlook, c'est pas vraiment le problème, mais c'est vraiment casse-c*****
