Well, that's a hard one because different people slice and dice differently. The summary I often use is:

Delivery: tell me how to use X at domain name Y
Discovery: tell me whether there is service X at domain name Y

Another way to do this is:

Delivery: I'm pretty sure domain name Y does X: tell me what I need to know
Discovery: I want to findo out if domain name Y does X
