+Postfilter for rpost to remove folded headers like `Injection-Info`
+before posting, written for the Debian *suck* package (and an INN
+with `sm`).
+
+Copy somewhere, e.g. to `/usr/lib/suck/postfilter.pl`, and add a
+matching `postfilter` option to `/etc/suck/get-news.conf`, like
+
+    postfilter: /usr/lib/suck/postfilter.pl
