More often I am reading about people running their own personal mail servers to prevent mega-corporations from processing/retaining their private data. I am somewhat new to the prospect of operating/maintaining a private mail server but have a generally sound knowledge of computers. My question is this: what sort of tools, literature, and tips would you offer to a person who wants to run a private mail server from his home connection? Is this sort of project feasible for somebody who doesn't have some formal training? Try to keep in mind that I am not an IT professional but I do have some basic know-how in the field.
