So, you have the pleasure of moderating a high-traffic majordomo list, and you want to speed up the action you take once you've scanned the message in your in box. Here's a couple of things to put in your .vimrc to help:
autocmd FileType mail nmap RQ [[c]]reject-quiet:wq
autocmd FileType mail nmap AQ [[c]]accept-quiet:wq
The stand for Reject Quiet and Accept Quiet respectively. Just hit those mapped key sequences, and your moderation is ready to go.
