If I wanted to keep it (sort of like retaining it on the server, but no longer in my Inbox on my Pre), I can always move it to another folder on the Pre that syncs with the like-named folder on my server/desktop email client.
I also have AOL (stop laughing, I've had it forever). On it, when I kill something on the Pre, it is retained on the web-based client until I physically remove it. Sounds like what you're looking for.
But, in the end, there are so few apps for the Pre- much less ones that are "upgrades" to the onboard utilities, that it'll be a while before you get the power you REALLY want. Sorry.
