The "tech-talk-bounces" address is added in the "Sender:" and - more

mailman's automated bounce-handling mechanism.
This fully complies to the relevant RFCs and works without any
problem on most mail clients and with ten-thousands of lists that are
handled by mailman world-wide.
What mail client are you using that shows this erroneous behavior?
If it's supposed to work like that it probably does.
I use pine when I'm at home, seamonkey when I'm at work.
