Yeah - it was me who asked the same a couple months back. Basically an & is a fully legal character according to the RFC, but you're depending on the programmers to follow the specs to the letter, both for your ISP and for the remote ISP.
In fact "@@\<@@\>@@"@atdot.co.nz is a valid address, but best of luck making that one work! Frankly I'd call it "best practice" to just use alphanumerics for the username.
