Delete my site and mailadress from Spam Blacklists.

Hello Freelancers, well, in march this year ( or earlier ) my business website has been hacked. On that time the site was not so good protected, so i think it was easy or only a question of time till this happened. In past i paid someone to grow up security, but now i know he has done nearly nothing. As the result the site was hacked. After that i paid someone who fix the spamcode and grow up really the security. Now i think its good protected. But the thing is, the site is used for month as spam sender and homepage and / or mailadress is listed in differen blacklists. Some blacklists delete a site automatic, if the problem is solved. But others not and thats the problem. Actually sometimes when i write mails to business partners i get messages like those back. host [login to view URL][[login to view URL]] said: 554 rejected due to spam URL in content or 451 4.7.1 MESSAGE Rejected by GREYLIST !! or has not yet been delivered to one or more of its recipients after more than 72 hours on the queue on [login to view URL] and so on. I found entrys here: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] Maybe you have another good tools or websites for checking. Actually its a big problem for me, because i don´t know often if messages reach my partners, clients, etc. So the task is to delete those entrys by filling out formulars, contacting blacklist owner, ... Using all possibilitys to solve the problem. It will be helpful if you have experiance with things like that. Hope you can help me. Best regards. The budget of this project is fix 50 Dollars and time is asap.
