Bulk Mailing Management - Fix issue

Right, the project is quite straight forward and clear. I already have a dedicated server all setup for email marketing. I am able to send emails etc... the only problem is I have soft-bounces from [login to view URL] and aol.de. I am using iterspire and looking for AN EXPERIENCED EXPERT to check my settings and make sure the emails are delivered to t-online and aol.de. You have to make sure i get CLOSE to 100% inbox, I have a server with 24 GB RAM and 1 Gbps uplink and 256 IPs. So make sure the settings remain the same or fix them if you find inconsitencies, but the main point of this project is for me to be able to INBOX those 2 domains - [login to view URL] and aol.de. Place your bids and let me know WHY i should choose you. I need a FAST turnaround : ie: less than 2-3 days
