The issue I hit was related to the SMTP server in bazaar.conf not
matching the email address that was being used. That should no longer be
an issue now that we're using both settings from the Bazaar

This might not be as reliable because of SPAM filtering. There are no MX
records for EC2 hosts, reverse hostname lookups don't work, and because
of other users sending SPAM the IP ranges may be blacklisted.
