Make sure he is encrypting to your key, not his own. You can decrypt anything 
sent to you using your own key (because you can decrypt encrypted emails sent 
between your email accounts). 

You don't need his key to decrypt a message TO you, you only need it to send 
an encrypted message to HIM or to verify his signatures. He needs your key to 
encrypt to you and verify your signatures. 

Him -> You = your key
You -> Him = his key

Can he decrypt an encrypted email from you? That will be encrypted to his 
public key and as he has his own secret key, he should be able to decrypt it.

He then needs to make sure he is encrypting to your public key before sending 
the encrypted message to you.
