Virtual server redhat 9 needs configuration (small job for experienced programmers)

Hello, I have rented out a Linux virtual server so that I can PHP scripts and use it as my mail server. I have 3 things to accomplish on the server: 1) install, setup & configure Sendmail or configure qmail (i have qmail running but not working properly). My mail server should accept and relay messages only if user/pw is accepted, and I need to handle 2 domain names ([login to view URL] and [login to view URL]) with aliases. 2) secure the server (I was hacked on another linux server recently). basically have one User/pw only and block any vulnerabilities. 3) setup the PHP file to run my code asynchronously... I use multiple instances of the PHP file on my other server and I need this one to do the same... the code is already on the server. running one PHP at a time works, I just need to run multiple instances at the same time. When I say PHP I mean the PHP file usually located in /usr/bin folder.. not a php script that I wrote. I need this done asap and I am open for suggestions, I would prefer someone I can keep in touch with because I will most likely need more help with my Linux server. unfortunately I am only a windows guru :( I will need to trust you with a user & pw to login to my server and you will also be able to see my code so I will need a NDA for my own security (code & pw's). Before you bid keep in mind that I would like the job done before Monday March 7th so please bid fast. PS: I will need explanations as to what you are doing on my server... I use msn messenger, unless you wish to communicate other ways. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
