Does Exchange (officially, via plug-ins, or otherwise) have anything comparable to Sendmail/Qmail adhoc aliases? IE, if your mailbox address is your.name@megacorp.com, you'd receive email sent to aliases like:
your.name-ignoredButPreserved@megacorp.com
your.name+somethingElse@megacorp.com
Basically, the mail server ignores everything between some character (like "-" or "+") and "@" for the purpose of matching a recipient address with a mailbox, but preserves it for downstream filtering purposes.
I could swear I once saw something mentioning that it could be done (at least, circa Exchange Server 2003), but I've never been able to find another reference to it, or anything that seems to be remotely related to it, ever again. I asked someone who (for what it's worth) was a certified Exchange Server admin, and got a blank stare. However, the same admin had never even heard of adhoc aliases in any context, so it's entirely possible that he just never recognized them for what they are. I know that Microsoft has a way of putting latent cool features into things that are "there" and "work", then forgetting to ever tell anybody that they even exist.
