We have a dedicated server with many small WordPress websites, microsites, landing pages and other business sites. It is a self-managed environment. We are looking for an IT person with extensive hosting / Linux / email experience to help manage our server. Recently we discovered that several of our website forms were compromised sending thousands of emails every hour. Our server's IP got blacklisted resulting in a huge loss of business as most of our email is rejected by most ISP's. We need an expert who can recommend best practice solutions, fix the problems and put security measures in place so these problems never happen again. We are looking for someone who not knows what they are doing but someone who can assure us they will be available to us when emergencies arise.
