server configuration

It’s a private project for CFC Infotech please don’t bid if you are not CFC Infotech. We are a leading email marketing service provider, but now we are facing Spamhouse Zen blacklist issue from few days. We use Cpanel , interspire along with PMTA as mailing agent. We have our system in place and need a consultant/configuration support to out from this problem. Payment Terms: As per discussion on Skype 100% mile stone will be created at the time of awarding the project. We need 1 week time for testing once server handover to us after setup. If SPAM HOUSE Blacklist issue will resolve and we will not finding this issue during testing then payment will be released. We mainly promote some financial offers like loans and all, we make all the SPAM keyword to Zero in interspire , even we are open for all the suggestion on send. Thanks
