		<description>There&#039;s nothing wrong with Ada, Matt.

I&#039;d be happy if email systems would recognize SPF for deliverability. I&#039;d be happier if they&#039;d block emails when published SPF records don&#039;t match the sender. I&#039;d be happy if Outlook would apply my rules *before* moving stuff to the Junk Mail folder.

I&#039;d love to have a flying car, but I am glad that everyone else can&#039;t have one. I am the only person I would trust with a flying car - the rest of you bastards would probably crash into my house.</description>

		<description>Um, why can&#039;t the post office filter out the junk mail that comes to my mail box every day?

Spam is part of life.  It&#039;s part of a free internet.  When a significant amount of customers demand a solution then one will come.  At this point however the internet is similar to the beginning of the industrial age. 

Back then there was tremendous discovery and implementation of thousands of new methods of production and no standards.  Today, there are standard ways of doing things that are common to almost all production facillities.  These methods and procedures aren&#039;t enshrined somewhere, they just exist as the &quot;best&quot; practice forged through a 150 years of trial and error.

In 20 years computing and the internet will be radically different than now. Look how far we have come in the last ten years.  When accessing the internet and programs becomes as easy as using a telephone then we will have arrived where we want to be.  Right now we are still toddlers in the internet age.</description>

		<description>We could significantly slow the spam if we just accept mail from official ISP servers, and block home computers from connecting to our mail servers. The money angle for the ISP&#039;s could be a fee to whitelist your home server, or a fee for a yourname@yourisp.com, or something similar...</description>

		<description>I&#039;m getting a &quot;Received-SPF: fail&quot; message in the headers of some of the mail I receive at Gmail.

I am all in favor of anti-spam measures, but something isn&#039;t quite right in this case.

I&#039;m glad Google is phasing this measure in slowly, rather than immediately deleting messages incorrectly identified as spam.

I think what is happening is:
* I use a forwarding service.
* Someone I know sends me email with all the wonderful &quot;SPF&quot; headers, and has a domain name has &quot;SPF&quot; all properly set up.
* My forwarding service forwards that email to my Gmail account.
* Gmail checks the &quot;SPF&quot; headers, determines that my forwarding service is not authorized to send email on behalf of the original person, and (incorrectly) concludes that my forwarding service is a forger, forging the original &quot;from&quot; email address, and therefore probably spam.

Is there some way to fix Gmail&#039;s implementation of SPF so that I can use a forwarding service, and it correctly distinguishes between people who forge the &quot;from&quot; adress and people who don&#039;t?

(p.s.: I suspect that
http://en.wikipedia.org/wiki/Hashcash
doesn&#039;t have this problem ...
would it be possible to update Gmail to support it?
Perhaps by letting my web browser calculate the Hashcash values in JavaScript ?
Or at least allow me to calculate the Hashcash values in some other program and copy-and-paste them into Gmail?

		<description>I had to think of this posting when I got a mail from my ISP at home: &quot;Swiss ISPs against Spam&quot; - http://www.stopspam.ch/

They&#039;re pushing SMTP authentication, which is a step in the right direction. I don&#039;t know many Switzerland-based spammers though :D, but it will help keep the zombie-pcs out of my mailbox. There&#039;s also a swiss ISP who proxies all port 25 traffic, dropping all spam-like traffic with a warning to the user (who can allow traffic from his connection, if it&#039;s legitimate).</description>

		<description>I&#039;m having a particularly nasty problem where someone has taken my domain name and is using it with random usernames to send out spam - e.g. sdfasdfsdaf@mydomain.org. 

Of course, most of these spams bounce, so my catchall account gets all the bounce notices. Most of the mail that ends up in my box is these bounced spam notices. (Plus the actual spam that&#039;s directed at my domain.)</description>

		<description>The &quot;corner case&quot; you mention, is pretty heavily used. How do you get around it when you use authenticated email?</description>

		<description>Matt, 

It is not only ridiculous but positively pathetic that in this day and age, we can&#039;t prevent spam or supply any kind of &quot;reasonable&quot; solution to bulk spam, personal attacks from competitors and dealing with the laborious, day to day problems which unwanted e:mail messages create for the average person doing business on the internet.

The only solution that I can forsee (considering my very limited technological abilities) is that anonymity has got to go! We should all PAY for our e:mail addresses and have various options available to us for private and/or business use.

I have gone to great lengths to protect my website from spammers ... yet they persist and have managed to not only break in and upload garbage all over my website (on every single page) but since being caught and having all their hard work reversed, they are now sending me messages daily and using my site to send them! I mean, come on! Some jackass actually has to sit there (on my site) and send every single message individually. 

How sad is that? They are pathetic losers with nothing better to do with their time ... but they still manage to tick me off ... and I guess (sadly) that seems to be their goal in life. Its unbelievable to me. WHO on Earth has the time to do that? Don&#039;t they realize the &quot;junk mail&quot; button is a very handy thing?</description>
