Personally I found that doing half-and-half works best for me. I put half of my email domains on an email provider for family use and for businesses that might block a self hosted server. I put the other half on a few self hosted mail servers for friends that do the same so that we have higher attachment size limits and as much storage as we have on our servers. The self hosted servers are great for exchanging PGP keys for use in Thunderbird and keeps the meta-data off servers at higher risk of mass-data-collection because of a few bad apples.
