a) Learn to live with it ;-)
b) Upgrade to 2.4 (if getmail4 will run with it)
c) Check to see if Python has a startup option for suppressing warnings

As to c) python -h gives a list indicating what I thought, that -W controls 
warnings, but gives insufficient info for me to use it, and I didn't find 
any more in the docs.  I hope someone else chimes in.
