Google's open-source RETVec anti-spam library

SpamSieve

I just wanted to be sure you saw this Ars Technica article about Google’s RETVec anti-spam library, which apparently has dramatically improved the spam filtering in Gmail.

This seems like it would be an upgrade for SpamSieve as well — and it’s open source! Perhaps it could be the headline feature for SpamSieve 4!

Yes, I’ve seen it. Too early to say whether it would be useful as part of SpamSieve (which already does some of that type of stuff, in different ways), but it’s certainly an interesting approach that I’ll be investigating.
