[apathy]

nb. The article covers Postini, which is like SpamAssassin/DSPAM (or Zimbra for that matter), only it costs money. There are some details that I am eliding, but fundamentally, that's what we're talking about.

Postini likely adds a great deal of value to Gmail by virtue of the vastly larger corpus. If that means that Postini is no longer a viable product for 3rd-party deployment, tough shit for the 3rd parties.

What I don't understand is why a Postini user (eg.) wouldn't just switch to Gmail for Domains and forward everything through an IMAP relay.

I originally replied (on autopilot) regarding the existing Google Docs/Applications framework. If they don't merge the entire mess into a rollup offering, I'm going to be flabbergasted.
