use reply-to-list instead of reply-to-all when
replying to the list
I have to thank GMail for not having such an option. I'm not a fan of
"clients" either, so I stick to the web interface. Frankly, it's
inconvinient enough to _not_ have a reply-to header since I don't ever
foresee a need to send a personal love message to a specific address posting
to a list topic.
