 <p>Well, it appears to work for me. I used this setting:</p> <pre><code>(setq gnus-parameters '(("regressions.*" (gnus-use-adaptive-scoring nil)) ("general-personal.*" (gnus-use-adaptive-scoring t)))) </code></pre> <p>Perhaps your regexps don't match your group names? The above regexps will match groups that look like <code>mail.</code> and <code>gmane.</code> (the <code>.</code> being a real period).</p> <p>The way I tested it was to enter each of the two groups and did an eval on the variable <code>M-: gnus-use-adaptive-scoring RET</code> - though you could also just do help on the variable <code>C-h v gnus-use-adaptive-scoring RET</code>.</p> <p>Perhaps what you want is not to turn <strong>adaptive</strong>-scoring off, but just to turn scoring off. AFAIK, adaptive-scoring is Gnus trying to <em>figure</em> <em>out</em> scoring for the articles, but not the actual <strong>use</strong> of scoring.</p> <p>So maybe this does what you want?</p> <pre><code>(setq gnus-parameters '(("mail\\..*" (gnus-use-scoring nil)) ("gmane\\..*" (gnus-use-scoring t)))) </code></pre>
