Actually, we use Spamassassin + Razor + Pyzor + Bayes + Spamcop right now, 
using Maia Mailguard as a front end ... I have 60k "unconfirmed spam" sitting 
in the database right now, most of which is scoring >20 ... I go through 
several hundred a week (the lowest scoring stuff) for all of the mailing lists, 
so that I'm adding to the Razor/Pyzor/Spamcop/Bayes database ... but that only 
keeps the mail from the lists, it doesn't keep them from the server(s) ... and 
I'm not just focusing on @postgresql.org email, but spam as a whole ...

How many on this list do anything to contribute to Razory/Pyzor/Spamcop, but 
make use of Spamassassin?  I know until I setup Maia here, that it was just way 
to much work to report each message individually ...

The thing is, 'checking for spam as it comes in' doesn't get rid of, or reduce, 
the problem ... SPF might not be it either ... but, if (in a perfect world) 
every mail server forced something like SPF, so that ppl could only send email 
through a legit mail server (ie. commandprompt.com email through a 
commandprompt.com mail server, gmx.net mail through a gmx.net mail server, etc) 
... would that not reduce the overall spam on the 'Net?

I don't know the answer to this, nor do I truly believe anyone here on this 
list can say with certainty ... all my goal was with adding a simple SPF record 
was to try and further reduce the possibility of someone using @postgresql.org 
for spam purposes, as well as providing more information to spam filters as to 
whether or not email addressed that way should be concerned legit or not ...

Until someone devises the 'perfect solution to spam', I would think that a 
series of 'less then perfect ones' would at least help combat it ...
