Figure the max and / or typical printed size. Calculate the 300 ppi value for that size. Write your boiler plate around that 'minimum' pixel resolution for submissions. Leave the option to just send originals, uncropped, if the photographer is unsure how to determine the pixel resolution. Set-up a transfer mechanism that takes the possible negative (automated) resizing out of the picture. This might be harder if you're accepting submissions from a random public, but doable.
Random public. Let me work on it and pull out a few more hairs.
