A "feature" which appears to be in many newsreaders (Mozilla, OE amongst 
them) which makes Pan think there is a uuencoded attachment when there isn
't.

The bug is triggered by starting a line with "begin[space][3 or 4 digits]". 
Despite the absence of a line with "end", or in fact any uuencoded data, 
Pan decodes it to binary data.

The message with Message-ID: <slrnbvghee.ool.ruben-news@its.blacklisted.nl> 
shows an example of the usage. Now, considering that in dutch, we are now 
living in "begin 2004", those words are not uncommon to use right now, or 
even in 2005 etc.

It could be that there needs to be a specific content-type header, in the 
case of the example "Content-Type:       multipart/mixed" was used.

The result:
begin 2004 is dan nog altijd geen geldig attachment zonder bijpassende
end die volgens de norm ook nodig is.
