All, I did some quick frequency analysis of the spam. I don't think it's a substitution cipher at the word level. Each word occurs only once except for 'Clarence' and 'chatting' which appears twice each. At the character level, the text conforms more or less to frequencies of English text. I don't have a German or Danish frequency table handy, and the spelling of Mathematik seems to suggest that one should look at those comparisons. It could be some form of stenography if it is even anything cryptographic. My guess would be a content fooler. I can't begin to guess why someone would send such a document. I pasted the first five or so words into www.dogpile.com and got mostly wordlists, porn sites and seemingly non-related sites. (AltaVista produced it's usual overkill of 1,102,396 documents.) Here's the results of my little perl counter.
