CVS: tmda/TMDA Errors.py,NONE,1.1 ChangeLog,1.111,1.112

Update of /cvsroot/tmda/tmda/TMDA
In directory usw-pr-cvs1:/tmp/cvs-serv12034/TMDA

Modified Files:
        ChangeLog 
Added Files:
        Errors.py 
Log Message:
Handle missing environment variables more gracefully.  Now, if SENDER
or RECIPIENT is not in the environment, tmda-filter raises an
exception right away which prints a warning and defers delivery.

Also introduce Errors.py which will hold all of TMDA's custom
exceptions.
