This should not loop, because you are not sending @host1.mydomain.edu
to @host2.mydomain.edu or vice versa.
However, the use of wildcards breaks address validation. See today's
email thread "Problem with virtual_alias_maps and backscatter" for
possible remediation.
That said, I think that the replicated message store would be the
better approach because the replication enforces consistency.
