Utilize Velocity MTA servers 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.
