> Google/hotmail/yahoo will reject emails straight away
Sorry, that's bollocks. Unless you are referring to a home dynamic IP broadband connection.
On a fixed-IP broadband link I have no trouble emailing people but on the other hand I do get a lot of spam (attempts) from people on VPS connections and yes, various sub-ranges of 'OVH' feature in my block-list, along with various compute-cloud providers, 'mail relay hosts' etc.
But aside from that, having a personal email server is not primarily a financial decision.
