I was looking into buying a Kindle as soon as it becomes available here (Rightpondia), but after reading the license agreement on Amazon, I'm not sure anymore.
Do I understand it correctly, that.. - in case the Kindle should be lost/broken or I buy a newer model, then all books are lost, too? - in case I switch to a different brand of ebook reader, I'm stuck with a load of unreadable books? - I cannot loan a book to a friend, except by giving him the whole device? - I cannot try to remove the DRM, otherwise Amazon will kill my service? - Amazon is snooping what documents I have on my reader?
If that's correct, then - sorry to say that - it looks like Amazon is telling me: "HA! WE SCREWED YOU!"
dnsbl/enhdnsbl is enabled for zen.spamhaus.org, [...] and sbl-xbl.spamhaus.org.
Save yourself (and Spamhaus) one query. zen.spamhaus.org includes sbl-xbl.spamhaus.org. so there's no need to query them twice.

I had a similar experience several years ago: No matter how you tweak the filters, it's wrong - catch 22.
Besides, spending several hours a day releasing mails from quarantine is not really an enjoyable or satisfying task.
So, here's what I did: We're also using GFI, so you can as well keep it. Maybe it's not the best system around, but I currently use a combination of postfix and RBLs on the perimeter and GFI Mail-Security and -Essentials on the inner network to handle ~150k messages/day for about 500 using. And I look at the quarantine folder just every other day...
I configuredthe system as follows: - I accept only mails from correctly configured servers (reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_invalid_hostname, reject_non_fqdn_hostname) I'm still amazed how many spammers think 'localhost' is a good idea. - No catchall account. One of our domains was badly burnt and just removing the catchall and standard accounts (except postmaster) eliminated ~ 30k mails/day. - RBLs. I'd recommend the zen list from spamhaus.com. - Greylisting. Most spambots still can't handle it.
Anything else is rejected. That alone gets rid of about 50% to 60% of all messages.
Bonus: Any 'false-positive' will get the rejection message, so the sender knows his message didn't get through.
Then comes GFI: - Virus/phishing mails get deleted w/o further notice. - Anything that MIGHT be harmful (like password-protected ZIPs) gets quarantined. If users complain about the delay, I give them an lecture about using PGP or X.509 to safely encrypt messages. - Anything else looking suspicious (based on bayes, other RBLs including my own, SURBLs, header checks and keaywords) gets tagged as spam and redirected to a spam folder in user's inbox.
The last part is the biggest change. It took me some time to get this through, but I feel the only person to make a decision about whether or not to delete a mail is only up to the user. My decision is based on my personal knowledge and is therefore error-prone (and if some people didn't believe this... well, let's just say my error rate increased;-)

Anyone wants to place an order?
Sorry, but no sympathy from me. For all of you who think that's too harsh: Have you ever calculated the damage done by spam?
Spammers steal your time: Sure, it's just 10 seconds to read a mail, make a decision and press the delete key. But it's not just *your* time, any other recipient also wastes 10 seconds.
So, if a spammer sends 10.000.000 mails per day and every recipients wastes 10 seconds, you get
10.000.000 mails * 10 sec/mail ~ 3 years, 2 months of wasted time.
In other words, every month this spammer wastes more than a full human lifetime. In my eyes, that's the same as if they would kill someone every month with their own hands.
Spammers steal computers to send their spam: Most spam is sent by trojaned machines. A small botnet able to send the 10.000.000 mails/day would likely consist of ~10.000 machines. Assume 3 hours to clean a machine and prevent it from being re-infected. Assume 10$ per hour. Total cost:
10.000 machines * 3h/machine * 10$/h = 300.000$
Spammers steal bandwidth: Though many people believe that bandwidth is free (flat-rate), it really isn't. ISPs or anybody with more than a DSL line do have to pay per GB. Even flat rates are just hybrid costing, basically an amount $x for the DSL line plus $y/GB multiplied by an average usage of z GB/month.
Now, for the spammer:
10.000.000 mails * 20 KByte/mail * 0.50 $/GB = 100$/day ~ 3.000$/month
Spammers steal ressources from the recipients: 75% of all email is spam. Without spam, all mailservers could be sized significantly smaller. Assume 500$ savings for smaller hardware. Assume 3 years (36 months) lifetime. Assume 1.000.000 mail servers.
1.000.000 server * 500$ savings/server / 36 months ~ 460.000 $/month
And that's just the beginning. There are the costs of spam-filtering software, costs of maintenance for hard- and software, costs of lost business due to false-positive filtering (be it manually or automatically), costs, costs, costs....
And let't not forget the costs of psychiatric treatment for admins suffering from burn-out syndrome due to constant nagging of their PHBs that they either a) receive too much spam or b) didn't receive an important email:-P
The only other box I have running that beats that is a Netware 4.x box. But that barely counts as a usuable OS:)
Hey, now don't you put Netware down;-) At least that was a reliable OS that didn't need patches every other day. Well, ok, you didn't need to patch anymore as soon as you had some version x.1... any Netware x.0 was always buggy as hell.
The last couple of NW 4.1 boxes I shut off last year at $ORK had uptimes of 400 to 900 days.
It was just like the song goes:
"They did what they were supposed to do,
it wasn't much, but it was enough."
