Optimum PMTA settings for Specific ESPs?

Hi Guys,

I would like to know if anyone knows the optimum PMTA settings for these ESPs:
1) hotmail.com
2) gmail.com
3) aol.com

I would like to know what the optimum settings for sending as much emails that will not result to a blacklist when warming up the IPs and afterwards are in your guys experience.

Thank you very much.
