It's now no longer misdirecting emails. I've been through logs to find out who sent me stuff, and I've sent texts to a couple of people in case I've missed anything important. I'll get all the misdirected stuff into the right place when I get home tonight, but if you're hoping I'm going to read something promptly that you sent me last night or this morning, you'll have to wait.
Edit (9am Monday): Now sorted out. All hail the power of awk/sed and netcat.
