Vulnerability Testing for Lotus-based Email accounts

My company is in need of a thorough vulnerability testing for our Lotus-based email accounts. Our goal is to improve our overall security and we have conducted vulnerability testing in the past. We need this work completed in one week in order to meet our deadlines. If you are a qualified professional with experience in this area, we would love to have you aboard. We expect you to be knowledgeable in the most up-to-date security techniques and be able to identify any potential weaknesses that exist within our system. We rely on our email accounts heavily as they are the lifeblood of our business, so we need this done quickly and correctly. If you think you have the skills and qualifications to get the job done, please consider applying for this project. Thank you!
