Yeah, this one wasn't the anti-spam filters that I manage (the
barracudas, our private RBL, etc) but spamassassin on oss.sgi.com.
So... Dunno. I took a crack at whitelisting Alex's from address in
spamassassin (though I haven't looked at it's configs or man pages in
about 10 years).

So true. I only happened to notice because I had someone (I forget who
it was several years ago) tweak SA on oss so that rejections get
forwarded to me. The idea was I'd look at those (stuff that the cudas
missed but spamassassin caught) and use that info to update our filters
(the filters that benefit everyone at SGI, not just oss).

Anyway, I don't always have the bandwidth to look at every email SA
on oss rejects and update spam filters (if possible) and just happened
to notice this one and that it wasn't spam.

I am a lot more aggressive with the filters for oss because it's
such a sore-thumb-target for spammers. For instance, there are large
swaths of yahoo IP space being blocked now (for oss only) because over
the years I only found one legit sender to oss from a yahoo IP - the
rest was all spam/phish. But I've only dropped in yahoo IP ranges that
I was seeing spam from. I've gotten aggressive with some Chinese IP
space too for similar reasons. If any of the senders you know of having
trouble might be in yahoo or chinese IP space let me know and I can look
in the logs, but I'd bet a doughnut that if they didn't get a bounce
then they're running afoul of spamassassin 'n not the filters I manage. :-(

There was talk a while back of taking oss out of SGI and hosting it
somewhere in "Da cloud!" (tm) and having someone else in the xfs
community own it, wasn't there? Anyone still looking into that?
