spamassassin not lethal anymore

[Russell L. Carter]

Howdy,

I've been happy using postfix+spamassassin for a long long
time, and it's always worked great.  However in the last
few weeks it's not been scoring spam high enough, and in the
last 10 days the spam is getting through in a torrent.   I
see a lot of scores in the 1-2 range, for what is obviously
spam.  I'm not really comfortable setting the threshold to
1, say.

I basically use it out of the box with a few tweeks for
performance, but I haven't changed anything in months.

Does anybody know if something happened upstream, or
was there some other relevant change, that I should be
aware of?  Starting here in case it happened at the
ports level.

Thanks,
Russell
