Hi guys..
Well, i am an IB student in grade 12 (last year in high school)
last friday, the IT technician in my school dared me to make a mail server (send and recieve emails)
and he said he can give me all the dns access that i need to make one..
All i know about mailling servers is how to send emails using php.. I made many and i know how to make them secure...
Now i want to build one but i dont know where to start from.. So please tell me what i need to know so that i build a whole mailling server that can send and recieve emails...
