Moved VirtualMailManager/Exceptions to VirtualMailManager/errors.
Renamed VMM*Exception classes to *Error.
No longer add the attribute 'message' to VMMError if it doesn't exist, like in
Python 2.4. It has been deprecated as of Python 2.6.
Also removed the methods code() and msg(), the values are now accessible via
the attributes 'code' and 'msg'.

# The user name and password to log into the pgsql server.
user = postfix
password = some_password
# The database name on the servers.
dbname = mailsys
# The SQL query template used to search the database
query = SELECT destination FROM postfix_relocated WHERE address='%s'
