Well, I got no further feedback, and the issue continues, a year later.

As I see it, it goes like this:

Spam is sent to the list. The list forwards it to subscribers. Some mail 
servers, like my ISP, point blank refuse to accept what is flagrant spam; 
not a doubt about it, it doesn't reach the spam folder. That spam probably 
breaks a rule such as having no valid sender domain, breaking SPF, 
something. I don't know for sure, because I can not see the logs of my 
ISP. But the oss.sgi.com admin can, surely.


The problem for me is that this list server automatically unsubscribes me, 
and I have to re-subscribe, posibly loosing interveening posts.


I suggest that the list server implements filters to remove those spam 
mails on entry, instead of forwarding them. Alternatively, other mail list 
servers send a probe email to the subscriber; if the probe bounces, twice, 
then the subscription is temporarily disabled. But they don't unsubscribe 
people because some "list" posts bounce, unless it is excesive.
