Hi All-- First, thanks to Timo for solving my last issue. I got dovecot up and running on one of my machines, and it does exactly what I want. Now I'm trying to install dovecot on an older box (glibc 2.0.7 Linux kernel 2.0.36), and encountering some problems: -- firstly autoconf/automake does not seem to correctly deal with the madvise function on this system. It detects that we don't

I have followed most of the steps outlined here: https://wiki.samba.org/index.php/Configure_NTP These steps I did differently are: * I did not install from source because the latest Ubuntu package for ntp available on Ubuntu 12.04 includes ntp-signd support already * I did not install Samba4 to /usr/local/samba, so
