Right.  Anyway, if I encrypted something using your DKIM public key, you could 
easily decrypt it using the private key.

please don't do that -- from a legal standpoint when resisting attempts
by Law Enforcement to request private keys, it puts you on very strong
ground to argue that a key has only ever been used for authentication
rather than encryption

also, by using the same key for different purposes you increase the risk
of chosen protocol attacks and other bad things happening, which is why
expert advice is to always to avoid loading the gun, even if you are
promising never to point it anywhere near your lower extremities
