Our list server has that quirk, such that
when you post a new item OR reply,
everyone on the list except you 
gets a copy/email. I think.

 Probably? the code/coder decided
that you'll know what you sent, and
that you have faith in the list server.
Also.... you can check the "archive".

Correct me if I'm wrong, anyone!
You did say: usually you get your own
copy/email usually, so it seems a debate.

I wouldn't know if tweaking the config
to be more giving is an option.
