moving a user without his client being aware of it. I like this method; it's cute, and solves a lot of the problems without a hell of a lot of work. (I've never tried it personally, though.)
It looks like a good solution, but it has a flaw; mining for the existance of email addresses is done with a simple DNS lookup. Almost like the VRFY SMTP command, not necessarily a good idea these days. Such mining can go undetected for a long period of time, and the washed email lists increase in value among spammers. It could be solved by using a differently named DNS entry though, so something like marc.crispin.deskmail.washington.edu, with some added logic for the end users.
We're looking to split our domain up so we have the externally visable DNS names and the internall visable ones seperated. Currently it's possible to mine for all DNS names in our domain and we want to change that.
