# What you can do with an MTA Delivery Policy

* [ ] Utilize [Velocity MTA servers](/docs/velocity-mta-basics/adding-a-server-in-the-backend-ui.md) for sending mail over your own home grown infrastructure.
* [ ] Create pools of IP addresses and individualized sending configurations for important mailbox providers such as Gmail, Yahoo, and iCloud.
* [ ] Place hourly and daily sending volume caps on IP addresses.
* [ ] Load balance mail volume across your IP pool by percentage allocation.
* [ ] Create individualized deferral waiting periods customized by the content of the SMTP response given by a mailbox provider. 
* [ ] Create a list of irrelevant SMTP responses to ignore, preventing the initiation of a deferral timeout.
* [ ] Throttle the number of simultaneous connections made to a mailbox provider's MX servers based on the MX domain instead of the domain in the email address.
* [ ] Automatically increase your deferral waiting period each time you receive a deferral message without any intervening delivery successes. 
* [ ] Pause mail if successful delivery volume has decreased below an expected threshold.
