The wiki is not the official documentation, which is at
http://www.exim.org/docs.html
I generally prefer to use the PDF format of the documentation, but the html docs at
http://www.exim.org/exim-html-current/doc/html/spec_html/index.html are good, too. You'll see that there are 60 chapters, and it's all very good quality.

Actually, there are four values: $demime_errorlevel, 2, 1, and 0. "if >" compares the first two values. If $demime_errorlevel is greater than 2, then "1" is returned. Otherwise "0" is returned.
> 2. condition = ${lookup{$authenticated_id}lsearch{/etc/mail/block_accounts}{yes}{no}} - why there is yes and no ?
Chapter 10 of the documentation covers expansion items, of which ${lookup is one. In this case, "yes" is returned when the lookup succeeds, and "no" is returned when it fails. The values there could, for example, be another lookup if you wanted. In each case, there are defaults, so you don't have to specify the return values if the defaults are what you want.
