[arpa]

You know what's really funny? That even with that overly agressive spam filter, once in a while (once a quarter maybe), it somehow manages to miss obvious BuY@@NiGERiAn@@Vi@gRa-Cia1is type of emails... which, by the way, my morally outdated spamassasin marks as spam.

"morally outdated" ?

I would make an educated guess that "arpa" is from EX-USSR and their native language is Russian. It's direct translation of idiom "морально устаревший" which literally means something is:

* Available for decades.

* Far from being top notch technology.

* Sometimes of course it's literally mean outdated. Like if you run older CentOS or Debian with decade-old packages.

So it's doesn't mean SpamAssassin is bad, but it's very far from state-of-the-art ML technologies that Google might have.

Bulgarian has that too: "Морално остарял"
