Design Custom MTA

Hello, We are looking for a freelancer or company to design custom MTA. We need following feature in MTA High Speed 1,000,000 messages per hour or more 8,000 concurrent outgoing connections or more Email Authentication SPF SenderID DomainKeys DKIM Throttle Limits Limit number of concurrent connections from a single IP to an ISP Limit rate of connection attempts (messages/hour) from single IP to an ISP Override rules on a per-IP address and per-ISP basis Group different domain names together in a single rule and limit IP Address Multi-Hosting Segment email through different IP addresses on a single server Individually assign each email message to a different IP address Advanced Email Routing Rules Create advanced routing rules that allow email messages to be routed through multiple IP addresses Route mail for different domains through different IPs Split between multiple IP addresses. Multiple methods of randomization available: address consistent, message consistent, or totally random Change routing rules for mail already in the queue Aids in warming up IP addresses: You can send a small amount of mail from a new IP address and slowly increase the volume as you build reputation with ISPs Bounce Processing Automatically parses incoming bounce messages to assign one of 19 different meaning codes Performs repeat counting of incoming bounce messages: Multiple hard bounces or soft bounces must be received before the address will be removed from your list This is helpful because sometimes ISPs send accidental hard bounce codes and soft bounce codes do not indicate a bad address, but if they persist over time then the address is bad User-configurable bounce counting requirements Intelligent counting: takes into account the number of email messages sent, so an address is only removed if the address is consistently failing Tracks bounce information for each mailing list individually Triggers an SQL statement or an HTTP request when an address needs to be removed from your list. This triggered action allows you to deactivate the address in your application Feedback Loop Processing Automatically parses incoming feedback loop notifications from the ISPs and determines the source address and email campaign that generated the complaint Triggers an SQL statement or an HTTP request when an address needs to be removed from your list. This triggered action allows you to deactivate the address in your application Advanced Reporting Each email message is assigned to a different send. This can be done automatically or based on a header that you provide. Reporting is provided for each send Reported for each send: Number of messages Number of successful and failed deliveries Number of messages still in queue Complaint ratio for each domain Bounce statistics Number of bounce messages for each reason code Number of hard, soft, and other bounces Number of addresses that were detected to be bad Domains producing the most bounces Click and open statistics Which URLs are clicked on the most Deliverability statistics: Which ISPs delivered mail to the Inbox or Bulk folder Weighted deliverability averages based on the number of messages actually sent to each ISP SMTP server statistics: Number of success, failures, and deferrals from each ISP Drill down to see failure and deferral messages from the ISP Transparent Click & Open Tracking Emails can be transparently modified to include click and open clicking links. Note: We have no limit budget, we will decide it after discus with you.
