[cobalt-users] installed upgrades, Qube2 sendmail has stopped working



Dear list,
On Friday I installed a couple of upgrade packages on our Qube2. It went down for reboot, but once it came back the DNS functions stopped working (nslookup, etc.) 

The Qube2 sits on our LAN behind a firewall/webramp that is supposed to be the Primary DNS server, as well as the default gateway. (I reset this device as well but nothing changed.) I can ping this device but nothing past it. 

Now everything is blocked up in the mailq and nothing is going anywhere, not just to the WAN but also the mail to the LAN. I think the configuration is the same as it was before....has this happened to anyone else?

Many thanks,
Delia Elder
