The documentation talks about "POSIX regular expressions", but the
examples use extended regexps. This should probably be clarified.

However, even if I remove the -r in the above sed call and escape
the characters +?(), it does not work. Character classes, such as
[:digit:] are available in regular POSIX regexps, to my knowledge.

So: the documentation needs clarification, but my problem remains.

Yes, I could just "text"-match against X-Spam-Flag (which I now do),
but I'd prefer it if the user could match against a spam
probability, e.g. already filter if SpamAssassin assigns 6 out of 10
required points.

Thanks,
