You are correct that it can be difficult to find what you are looking for if you have absolutely no idea what it is called.
However, it doesn't look like you even tried!
Just Searching with "Config db" which is how you described it to us:
I cant understand this lines because i didnt know where put the name of the acount where the mail has to be sent. By the way anybody have or do or know a manual of all config posible to do by config or db ? because the sme manual is limited to the server-manager web console, but its important document all the wonderfull options of the sme7.
Brings the result back on the first page.
Byte then told you that raymitchell made the post, so you repeat the above search with raymitchell as the author.
Now the page you are looking for is only 4 from the top!
