buckaduck was here last month. You may or may not class that as being still around.
You haven't linked to the post in question, but perhaps you meant this one? If so, it would be pretty trivial to have your output file named something other than "message.txt". One of the replies indicates that attachments are already catered for (and a cursory inspection of the script confirms this). That just leaves your additional NSF file which I presume you could re-import into your stock email NSF before running the script.
