Alright, I got it all working now. Not sure how to change the time zone with config files, so I just used sysinstall to change it to MST (time zone is arbitrary, but since this is the zone I live in, it's convenient for me). Then I used ntpdate to sync it, and it's working well now. Thanks for pointing that out to me. I just thought that CET was central time :) On Sun, 27 Feb 2005 10:36:35 +0100, Anthony Atkielski <atkielski.anthony@wanadoo.fr> wrote: > Pat Maddox writes: > > > I've included the headers of messages from both Gmail and Hotmail, to > > show that it's not on Gmail's end.
