    151151
    152152 * [wiki:how-to/servers/add_ip_allocation Allocate new IP address]
    153  * Create a Host record that ties the IP address to the host name (e.g. rustin.smtp.mayfirst.org or cleveland.smtp.mayfirst.org). Set the time to live to 86400 (it's important to have along ttl since some providers do a reverse DNS lookup of the sending IP address and will punish you if the ttl is too short).
     153 * Create an A record and ptr record that ties the IP address to the host name (e.g. rustin.smtp.mayfirst.org or cleveland.smtp.mayfirst.org). Set the time to live to 3600 (it's important to have along ttl since some providers do a reverse DNS lookup of the sending IP address and will punish you if the ttl is too short).
    154154 * Add this instance to either rustin.pp or cleveland.pp. Be sure to use rate limiting when warming up a new IP address. See the yahoo relays (which are permanently rate limited) for an example of how to do it.
    155155 * When you are sure it's configured properly, create an A record from the $instance.smtp.mayfirst.org to the IP address. When adding a new IP address, you may not want a lot of email to go to it initially. Instead, you can "warm it up" by controlling the ratio of IP addresses in use for the given domain. For example, you can add give A records for the existing IP address and one A record for the new one. After month, remove one of the old A records and add a new one for the new IP address.
