Hi all,

Here's my take on this.

Both Gnome and OpenMoko use Mailman for their mailing lists, which means
that a simple search query like this:

  http://www.google.com/search?q=%22Below+is+a+listing+of+all+the+public+mailing+lists%22

...will bring up lists of mailing lists, out of which the mailing list
addresses can be easily extracted. Since these pages link to the mailing
list archives as well, it's not that hard to find an e-mail address that is
likely to be a member of the mailing list, and hence mails coming from that
address do not hit the moderation queue and are let through immediately.
Perhaps the spam bots even prefer mail addresses ending with the same top
level domain as the mailing list address (this happened to Gnome at least),
which even further reduces the chances that the mail will end up in the
moderation queue.

By the way, in the past few weeks, I already discarded a few messages like
these from the evince-list moderation queue (I'm moderating that list). From
what I remember the From header did not contain a @gnome.org address, but
I'm not hundred percent sure about this.
