In 2.5 the email version was bumped to 4.0.2 just before release but
after the maintenance branch was set up.  The bump was not backported
to trunk, and 2.6 went out the door with a version number of 4.0.1.
I bumped this to 4.0.2 because of a behavior change, but that makes
it look the same as 2.5.  So bump it again to 4.0.3.
