configuring email server: Setting Up SPF, SenderId, Domain Keys, and DKIM

Hello, I startet a new server that is running with Debian Squeeze and Postfix and this time I want to make it right with email sending. So I need someone to set up SPF, SenderId, Domain Keys, and DKIM for all my ten websites. Also configuring and installing everthing else that is supporting all anti-spam standards and using other methods and possibilities that lower the risk of being marked as spammer and are improving deliverability of emails. For DKIM I want that all outgoing emails are automatically signed with a signature. Also I have several IP adresses with the server and I want to assign each website with his own IP adress, meaning that also the emails should be send through that IP. For example website A should be available through the IP address 1 and also all outgoing emails from website A should be send through IP address 1. Website B should have the IP address 2 and also all outgoing emails from website B should be send through IP address 2 and so on. In addition maybe a bit of consulting would be great, when there are other options and possibilies for better and more secure email sending, because I am not really familiar with the email sending standarts and what else there is to be considered. I want to stress out that I need someone who is capable of doing all the things mentioned above and who has experience with setting up a mail server and already performed such optimizations. So if you are interested in the job, please send me your portfolio, where I can see what work you have already done. Also you need to be highly trustable and reliable for this job. If you need further information, just send me a message.
