Possibly what's going on is that Mailman has noticed that it's trying to send
that email address _two_ 'CCTalk' copies: one for your actual CCTalk
subscription, and one for your pseudo-subscription (via CCTech). It thereupon
automagically suppresses the second copy.

Nope, my guess is you'd wind up with one copy (from your 'real' CCTalk

Go ahead and try it: you can make sure you don't miss anything by looking in
the archive (which is how I read the list: I don't actually get _any_
copies... :-)
