Not a good idea. It's a best practice to refuse *all* email traffic
out of Amazon's cloud because (a) it's a prodigous source of spam and
other forms of abuse and (b) Amazon absolutely refuses to lift a finger
to address the problem. (Just try submitting an abuse report and notice
all the hoop-jumping they've put in the way in a quite obvious, deliberate
attempt to make it as difficult as possible.)
