Running your own mail server almost isn’t an option any more.
I ran one from home, but lots of big email servers wouldn’t accept mail from me - for example I could not send to hotmail or gmail users. They blocked me, because the domain name of my email server (rustybrooks.com) did not match the reverse lookup of my IP address (something-random-dhcp.att.net)
So my choices would then be to rent a dedicated server at Rackspace or something, pay AWS for mail services, or I suppose get a static IP address for home. All of these cost money. Running my own server at home on a fiber service didn’t cost me anything extra except my time.
Oh well. I pay google a buck or two a month to do it for me now.
