LISA Conference

I am headed to Dallas TX for the USENIX - LISA conference. I am not staying the entire week, just through Tuesday. I will be attending High Capacity Email System Design, and Tuesday I am going to the Postfix Configuration and Administration. I am excited about both of them. We are currently using Sopho's PureMessage for Unix which I have been very happy with. I deployed it 18 months ago on a Sun 280R with 2-900Mhz procs and 2 Gig of Ram. 6 months ago I upgraded it to 8 Gig of Ram. It is currently way past capacity. I have configured it to quit scanning email when the load gets high enough so that it can catch up. I am replacing it with 3 servers each with 2 - Quad Core 2.0 Ghz Xeon processors and 8 Gig of Ram. That should keep us spam free for a while. I am also going to be adding either Mailman or Majordomo for a list serve. I am currently using LDAP groups for this, and I am starting to need a more robust solution.

I would also like to offer our users the ability to to SMTAUTH via TLS. Sophos includes a version of either Sendmail or Postfix, but neither are compiled with very many options.
