Ah, no. Good point. I can see a sender, an IP address and a recipient (or a
list of recipients). This isn't going to work in two cases:

1. A sender's host is a spambot. It spams me (and other recipients) in an
unwanted language a few minutes before the sender sends me a legitimate
email in a wanted language.

2. Vice-versa.

I guess the likelihood is increased in the event that the spambot is using
the sender's address book.

So, we'd have to implement this by storing the sender, recipient, IP
address triple. It's not error-proof, and it is quite complex. I guess
sticking to single recipient messages would fix 99% of the problem
(reliably) at a cost of 1% of the work.
