To add a short personal story to this discussion; I run my personal mail server at home, using XS4all (a Dutch ISP). Very low outbound rate, I think on average 10 emails a day. Using SFP / DKIM / DMARC. Most of my mails get through without problems. I guess XS4all IP blocks have a good reputation as the provider is very security aware and permits users to run their own servers using a dedicated IP address with a reverse DNS hostname. Unfortunately XS4all seems to get absorbed by KPN.

Of course setting up your own mailserver is somewhat time consuming, but there are many tutorials. In a perfect world one wouldn't need a static IP, but being part of a somewhat chaotic federated communications network has a price. Setting up your own XMPP or SIP server also relies on DNS and using those services without a static IP is difficult.

I feel that some of the discussion about running one's own mail server should be more appropriate on the mailop mailinglist. It is not a protocol problem. The only thing I don't like for small setups is that a few newer anti-spam methods rely on https resources at the sender's end.
