Reducing spam on alsa-devel

Reducing spam on alsa-devel

[Philip Prindeville]

Anyone know how to contact the list administrator?  I tried sending
an email to alsa-devel-request but never heard back.

I'd like to work with him/her to improve the SpamAssassin settings
and cut down on some of the spam we're seeing on this list.

Thanks,

-Philip

There is very little spam on this list (less than 10%).  I doubt it can
all be eliminated without some false positives.

Anyway check the message headers for instructions.

The list headers say to contact alsa-devel-admin, which I've already tried.

10% is fairly high.  A lot higher than other open lists that I subscribe to.

"Some false positives" isn't unacceptable.  Usually the person can
figure out
why he got the false positive, and repost in such a way that he doesn't.

About 90% of the spam that does get through on this list, I'm able to
identify
just from the Subject: line alone.  So changing the subject would be enough
to get it through...

I agree that the spam level on alsa-devel is highly rediculous. I
stopped reading it because i have to sift through too much
non-content.

The spam has been drastically reduced from several months ago.  Maybe
whatever filter was applied could be dialed up a bit?

Do you notice any pattern in the spam scores (see headers) of the
messages that get through?

Well, I have filters on my own system that reject messages being delivered
for alsa-devel if they look too much like spam.

A lot of these are private rules I wrote myself.

But every once in a while I'll see a message that should have been rejected
by a standard SA install but wasn't...

Could have to do with the custom scoring or with the way that
auto-whitelists
work...

You also might not have a complete SA install, with SPF turned on (for
instance).

I could share my rules, but it would have to be out-of-band, since any
spammer
could then look at the list archives and figure out how to get around them.

Hence my comment about wanting to reach the list admins directly.

to the one from Sourceforge's server:

I am a user of GMail, which I think limits my options for viewing
extended mail headers.
