Thanks Gerald, none of your solutions worked, but I've just figured it 
out now. In the expression the space should only be added at the end, 
*not* at the beginning! In the Received header the first character isn't 
[[:blank:]], but "f", so I've been chasing the wild goose all this time 
because I started with the wrong assumption :)
Sorry for the noise, all good now.

Cheers,
