Dear sir, I am Thomas, 25, French, IT master degree and currently working as a linux system engineer @ a french ISP. I always used to like Linux, I've been using it for more than 10 years now, and began programming around that time too. My sharpest skill is Debian Linux, though I'm able to work with other Linux (Redhat, centos) as well as BSD. I have strong troubleshooting skills and already encountered this error. I know mail servers/postfix pretty well. I would like you buy myself a bike so need a bit of money, if you help me with this i'll help you with your project. Take a look at my reviews, used to work when I was unemployed and made nice projects. You can trust in me. Awaiting your private message for more details, thanks if you read this! PS: I work 9-19 Paris time, please let me enough time to answer :(

No need to pay until I finished all required your tasks I have more than 9 years experience in MS Tools, Windows Server, Exchange Server, Firewalls, Network, Linux
