In case you haven’t heard, the GNOME Foundation Hired a System Administrator, Christer Edwards.

Christer was already a volunteer GNOME sysadmin, so he already knows a lot about the GNOME infrastructure. He fixed various things already, but I’ll leave it up to him to blog about that. The one thing I really like is that he cleaned up the Logwatch output for the various hosts that GNOME has. After which I requested he cleaned up the menubar (mail.gnome.org) Logwatch output (was 3.5MB), which he did :).

So now finally we can easily see some data for mail.gnome.org for Monday September 20:

Note that mail.gnome.org is the mailhub for GNOME. All outgoing (mailing lists, bugmail, etc) and incoming mail (spammers, spammers, spammers and some minor valid mail) for all machines is handled by mail.gnome.org. From the logs you can easily see that we get regular distributed dictionary attacks (high number of unknown users errors), plus Greylisting that was deployed (also done by Crister)

PS: As you noticed, there is now a GNOME sysadmin blog. It is syndicated at http://news.gnome.org/.
