We are looking for someone able to guide us in the best infrastructure for postfix for maximum effectiveness. Also, we are looking for the best practice in postfix configuration depending on the strength of the server. The goal is to have the best ratio for sending simultaneous e-mails.
We are expecting also a good tool (GUI) to monitor the effectiveness.
We will provide you with a clean vps where you will perform the setup and give us the benchmark test that fulfills the requirement of max messages per hour (expected 800000). Then we will copy the configuration to our main server and test it out before releasing out the payment.
We are the owner of one postfix already online and working well (DKIM and all declarations have been made). We want to fine tune as possible to send the maximum of emails in the minimum time. When we request for the best practice we are expecting a comprehensive load-balancing/failover diagram over postfix. Also, we would like to install a good tool to monitor the email activity, with a quick explanation of how to install it and a guide of use.
