I have this annoying guy that post on a email list I'm on. Is there some easy way to ignore the fellow in Gmail?
You can put in a filter that either automatically deletes the emails from him (pretty drastic) or better yet just label & automatically archive them. The advantage of the second way is that you can still easily access the emails should you wish, but they do not appear in your inbox.
You can create the label at the same time as you create the filter.
