.... the DKIM page was the first one that came up when I tried it....
That's another thing, email bounce from Google said that I need SPF or DKIM, did not know which one is preferred method on SME Server.
Jean-Philippe Pialasse did not say anything and helped me much..much more with just one link, than long sentences of nothingness.
Helpfulness level:- Jean-Philippe Pialasse +1
