550-5.7.1 "unsolicited mail"

Until a few weeks ago, I was able to send email mostly anywhere using my local postfix.  To me that's the most convenient configuration because I frequently switch networks and I don't like to change my SMTP server every time.  So I configured postfix on my laptop and I'm using "localhost" as my SMTP server.

But suddenly, a few popular email servers such as GMail or Yahoo now seem to reject my email with this message:

<foobar@gmail.com>: host gmail-smtp-in.l.google.com[66.249.93.27] said:
    550-5.7.1 [11.22.33.44] Our system has detected an unusual amount of
    unsolicited 550-5.7.1 mail originating from your IP address. To protect our
    550-5.7.1 users from spam, mail sent from your IP address has been
    550-5.7.1 rejected. Please visit 550-5.7.1

    Email Senders Guidelines. u1si8404313uge (in reply to end of DATA command)

Err, what should I do here?  I'm pretty sure that no SPAM has been sent from my IP.  What's "unsolicited mail" anyway?  Do I need to ask one to solicit an email from me so I am able to write him? :-)  This stuff is quite annoying...  Like any security restrictions, SPAM filters affect legitimate use as well.

I'm now forced to login to GMail when I want to send a message to someone at GMail, which kind of sucks..

    Try signing your message with DomainKeys. That should make gmail more torelant wrt your mail.

    I have with great interest studied your website/information. It is nice to get confirmed by DM Gurus that the working methods I use right now is close to the policies as mentioned by you. Most important of course is proper planning based on a strong belief that DM is a strong marketing tool if used correctly. I think there are many traps along the way and the consequences have to be analyzed carefully before the final solution is made. Today many marketing tools are available and actually they compete so it needs a lot of expertise to pick up the best, and the best choice is the one that serves the clients interest, not the DM Company.

    I've been struggling with the same problem, and haven't found any relief from Google.  We're new on the web, and may have had some deployment issues in the past.
    I've installed DKIM on my server, gone through the steps, and am waiting for my DNS records to propigate.
    I'll check in and report!
