Description of problem:
The new package ftp://people.redhat.com/jdennis/postfix-2.0.6-11.src.rpm doesn't
build on RedHat 7.2 because it lacks support for db4.

Version-Release number of selected component (if applicable):
postfix-2.0.6-11

How reproducible:
Always

Steps to Reproduce:
1.rpm --rebuild postfix-2.0.6-11.src.rpm
2.
3.
    

Actual Results:  It doesn't build because db4-devel is missing.

Expected Results:  The package should have used db3-devel instead.

Additional info:

Of course, this is not a bug because the package isn't intended to build on
RedHat 7.x. However this small patch makes it build on 7.x and 8.x.
