Se observarmos bem o modo como as ferramentas Bogofilter e Spam Assassin trabalham, veremos que elas funcionam por meio de um treinamento de um modelo estatístico para depois conseguir determinar automaticamente o que é classificado como SPAM, e ao receber novas mensagens, enviar direto para a caixa de SPAM. Talvez hoje em dia poucas pessoas usem clientes de email locais, mas para esse público essas ferramentas continuam a ser grandes aliados no combate ao SPAM.

No entanto, vejamos que nenhuma das duas é propagandeada como um mecanismo de IA. Perceba, portanto que o rótulo "IA" é subjetivo, e no meu modo de ver, esses dois projetos acertaram muito em evitar esse rótulo, por tão vago que é.

E a propósito, um interessante artigo comparando os dois [1].

If you're using #SpamAssassin, now is a good time to stop relying on Validity's Realtime DNS Block Lists ("Validity Zone File Access"). Free-tier users are being threatened with severe usage limits unless they arrange a call with Validity's sales team. #DNSBL #email #BaitAndSwitch 📩 💔

@santiago FWIW, the automated rescoring that we (the SA Project of #TheASF) do for the default rule channel works on the assumption that the threshold is 5. If you reduce the threshold you should put in proactive work to improve (i.e. reduce) the scores of mail that you value.

E.g. I use a level of 4 & I use the supplementary KAM rules channel. I can only do that because the vast majority of the legit mail on my server is aimed at "more_spam_to" addresses.

If you use #SpamAssassin and actually want mail sent to you from a subdomain of #wordpress.com, you will want to add that specifically to your local welcomelist. We've had reports of signed spam from such domains, so we cannot leave the wildcard in the "default welcomelist" in SA's rule channel.

This change just went into SVN and will take a day or two to appear in the channel.

Ah ben la dernière, c'est #Validity qui veut du pognon.

Donc, pour désactiver ces parasites dans #spamassassin :

ifplugin Mail::SpamAssassin::Plugin::DNSEval

header RCVD_IN_VALIDITY_RPBL eval:check_rbl('custom', '127.0.0.1')
header RCVD_IN_VALIDITY_SAFE eval:check_rbl('custom', '127.0.0.1')
header RCVD_IN_VALIDITY_CERTIFIED eval:check_rbl('custom', '127.0.0.1')
header RCVD_IN_VALIDITY_RPBL_BLOCKED eval:check_rbl('custom', '127.0.0.1')
header RCVD_IN_VALIDITY_SAFE_BLOCKED eval:check_rbl('custom', '127.0.0.1')
header RCVD_IN_VALIDITY_CERTIFIED_BLOCKED eval:check_rbl('custom', '127.0.0.1')

endif

Yippee-ki-yay, motherfucker !

Der Ceph Orchestrator – Container für Storage | Heinlein Support GmbH

Seit Ceph Version 15 aus dem Jahr 2020 gibt es den „Orchestrator“, der die Komponenten in Containern auf den Cluster-Knoten ausrollt und verwaltet.Inzwischen sind eine ganze Menge Dienste hinzugekommen und es lassen sich sogar eigene Container-Instanzen aus eigenen Images verwalten.Der Vortrag zeigt die grundlegende Funktionsweise und baut eventuell vorhandene Bedenken gegen den Einsatz von Containern im Storage-Umfeld hoffentlich ab.Er ergänzt mit einem Ausblick auf die Storage-Integration mit Kubernetes.

Anyone who followed me in recent days for my #SpamAssassin lore and related #spam and #InfoSec hot takes should know that I'm one of those "everything is political" guys who does not believe in falsely limiting myself...
I'm a good one to mute for the day when you've heard enough terrible news.
