As other messages have pointed out, POP-before-SMTP is not the best way 
to do things.

But, you can solve the problem by requiring that your users submit mail 
not to port 25 but to the submission port (587).  Then, you can exempt 
anything that comes into that port from greylist, since you know it has 
passed your authenitcation test.

This is the right way to do things no matter what authentication system 
(POP-before-SMTP, SMTP AUTH, etc.) you use.
