I&#x27;m running my mail server and it&#x27;s not that hard IMO. There are a lot of guides, standards are easy to understand. I can&#x27;t say how much one would devote to setup his server, probably few hours should be enough.<p>Gmail marks my mail as spam, for new recipients, though. I don&#x27;t care, every gmail user usually checks his spam anyway and when I do care, I&#x27;ll call person to ensure he got my mail, regardless whether I use gmail or my server.
