Now, unless you arrange for your outbound email to arrive from a server operated by a large email provider, your deliverability is probably low.
You have to make sure your mail is delivered from something that looks like a server (e.g. not on lists of known dynamic IP blocks, has proper reverse dns) but you don't have to use a "large email provider".
Been running my own email for years with few problems.
