So my Mac OSX server died last night. Fortunately I had a Raspberry Pi 
sitting around so I loaded it up and put Surgemail on it. I was able to 
recover all the mail files today so that's up and running, but I have lost 
the license key.

Sigh.

Is it anywhere in human readable form in one of the many files in the 
surgemail directory and what's the process for re-activating it? Or is there 
a file I just need to copy over?

I can pony up for a new key if necessary (I only have the 10 person license).

Thanks,
Russ
