I couldn’t find anything here on the bbPress site… I would like for email addresses that appear in posts to be transposed to something like “user [at] domain [dot] com”.

Is there a plugin, or an easy way to do this?

Take any plugin that modifies post text and change it to run a preg_replace over the text.
