Additional details on each of these PowerMTA features is available for a more in-depth review.
VirtualMTA Technology — VirtualMTA technology allows senders to control the source IP address for each single message. Each VirtualMTA performs its delivery functions independently; therefore, as long as the source IP is not blacklisted, your message has a higher chance of being routed to the inbox.
Delivery Policy Management — PowerMTA lets you set your configurations globally, per recipient domain, per campaign, per client, per “VirtualMTA”, etc. to help meet ISP standards including:
- Number of simultaneous connections
- Number of messages per connection
- Number of delivery attempts per hour (throttling)
- Retry period and bounce period
- Authentication method
In addition, PowerMTA provides support in these areas:
- Ability to break connections of lower priority queues
- New IP address warm-up feature to help build reputation
- Ability to pause queues and delete or re-start
