Key features included in the release: - Scheduled Delivery Control
PowerMTA now supports the ability to schedule deliveries via a header. This may be very useful for instances when it takes a long time to build a campaign, or if you need to adhere to strict delivery windows. - Precached domains support
To help optimize DNS usage during peak sending times, PowerMTA now offers the ability to precache predefined domain names to ensure the DNS name is always available. - IP Rate Limiting
IP rate limiting allows for controlling the number of attempted recipients on a per-hour, per-minute and per-second basis for each IP address for each domain/VirtualMTA. This is primarily used by sites that define multiple IPs in a single VirtualMTA, and that want to limit the attempted delivery rate for each IP address in the VirtualMTA to the respective domains. One can also specify the maximum number of connections to be opened for this domain during the specified time period per IP per domain/vmta. - Auto Cold VirtualMTA Rate Increase
PowerMTA now supports the ability to auto-increase cold VirtualMTA mail volumes with a list of daily limits. This makes it very easy to have a set it and forget it configuration for warming new IP addresses. - Address Suppression Lists
Addresses in the suppression list are rejected (or turned into bounces, depending on options) during submission. This is very useful for sites that do not have complete control of the list to which they are mailing.
