Thanks for the link Graeme. I have done some poking around and it appears that the file names have changed on SME 6.0 from:
/home/e-smith/ssl.key/secure.mydomain.com.key
/home/e-smith/ssl.crt/secure.mydomain.com.crt
To:
/home/e-smith/ssl.key/myserver.mydomain.com.key
/home/e-smith/ssl.crt/myserver.mydomain.com.crt
For anyone using the Howto you must modify the names in the howto to correspond to the 6.0 convention.
