Granted, but tmda should point out this limitation since it doesn't have 
a workaround for it.

I couldn't get HOME in tmdarc to affect os.path at all.  Don't quite 
know why.  What I did find that does work is to create another 
environment variable DATADIR and put the path to the user's home 
directory there.  Then in tmdarc I put the line:

DATADIR = os.environ['DATADIR']

And changed all the file names in the settings to be of the form:

filename = DATADIR + original name without the ~/.tmda

At least the pending messsages go in the right directory now.  However, 
on a 1 GHz machine it takes several seconds to process a 2 line message.  
I am a bit concerned about performance as our mailserver processes 
hundreds of thousands of messages daily.  Python reads a ton of junk 
before it starts to do anything.
