[webmin-l] DKIM global default key

[jsmosc <js...@ma...>]

Hello,

Needing to setup DKIM key for a virtual server in the 
Virtualmin/ServerConfig/DomainKeyOptions, I see that I can use the 
"global default key".

Where is this  "global default key" on Webmin? Unable to find anything 
in the Webmin various menus :(

I already setup a few domains with this but my memory fails and I am 
unable now to remember where this global key is :(((

Thank you!
