[Exim] Exim on which CD-ROM?

Ok. I've heard that Exim (which was formerly on the powertools) has been moved to the "Applications" cd in RedHat 7.2. Which Applications CD? I was thinking of buying 7.2, but I want to get the least expensive release that actually contains the exim RPMs. So is it 7.2 Standard or 7.2 Professional that has it? (Obviously, if standard has it then professional does too, but thats beside the point).

thanks in advance!
