We are a email marketing company and we want to start a business similar to Mailchimp.com. We already have the software to manage the newsletters (the software is Oempro from octeth.com company) and we are now looking to find a Postfix expert who can setup and optimize our server for bulk / mass mailing.
We would like to have a Postfix working similar to Port25 PowerMTA or GreenArrow, but they are both very expensive softwares.
We will buy a new and clean dedicated server with a dedicated /24 IP Block just to host Postfix and the installation and setup of Postfix will need serious work in order to make it work in a similar way that commercial MTA's work, in order to meet all ISP and Anti-Spam regulamentations.
Bellow i leave just some of the features and things that have to be setup and optimized on the Postfix server:
-> DKIM + SPF + ReverseDNS + Sender ID Setup
-> Number of simultaneous connections
-> Number of messages per connection
-> Number of delivery attempts per hour (ip throttling)
-> Definining sending limits based on ISP and/or IP Reputation
-> New IP address warm-up
-> Ability to create VirtualMTAs or other way of ip rotation allowing to segment mail-streams as necessary. Each VMTA must have its own IP address and delivery policy.
-> Fully Integration with Oempro allowing to segment and separate different types of Transactional from Bulk emails. On our IP block some IPs will be reserved and used only for Transactional emails and others just for Bulk emails. Oempro allows to add Email Message Headers so this can be the way Postfix can identify what kind of message it is and send it using the correct ip pool.
-> Testing with Oempro to ensure that all is working ok.
:: Important Note ::
Please just respond and/or apply to this work if you have a lot of experience with setting up postfix servers for email marketing and also Oempro experience in order that the integration between the 2 systems can be done in a perfect way. I remind you that we are looking for someone that can setup Postfix on a server with a /24 IP Block to act and work similar to how commercial MTA's like Port25 PowerMTA or GreenArrow does.
