Our current mail server uses one ip address
We are distributing a daily email to our subscribers -- which generates a
large burst of email. We have main.cf configured as follows:
sender_dependent_default_transport_maps =
randmap:{r192,r193,r194,r195,r196,r197,r198}
smtp_connection_cache_on_demand=no
