      Hello,

      Since couple of days, it looks like my postfix server goes mad,
      maybe because of some ugly spam i receive, but then after such
      mail is received, my postfix logs lots of warnings every second:

      mail_version is 2.0.16-20030917, patched with CDB support , compiled from source
      OS= Linux 2.6.13.4 / Debian , x86

      This is a small server at home, postfix configuration and version (mail_version = 2.0.16-20030917
      patched with CDB support, yes i know it's old) haven't changed for about almost two years.

      Time for me to upgrade ? :)

      Thanks,

      Philippe
