I got to the startssl site ok, but failed at that point because I haven't 
yet managed to get claws-mail to actually fetch the mail while I am booted 
to 12.04.2 LTS.

Chicken/egg problem.  So I guess I'm stuck with SSC's ATM.  And because I'm 
doing full shutdowns to swap drives in a hot swap cage, I am killing my new 
and old drives with all this powerdown rebooting.  Probably 30 such cycles 
in the last 10 days. :(

Thank you for the help, its very much appreciated.

Cheers, Gene
