primary_hostname = iris

relay_domains_include_local_mx = true
sender_verify = true
receiver_verify = true
remote_smtp:
  driver = smtp

other settings are default

my dns server configured as following:
@               IN      SOA     mipsa.ciae.ac.cn. root.mipsa.ciae.ac.cn. (
                                1.1     ; Serial
