Hello,
I am thinking about setting up my own private imap and smtp server (with DKIM/SPF) for my small business on a virtual host at DigitalOcean or Amazon Lightsail (or something like that). No email campaigns, no transactional emails, just for the business communications, 10-20 outbound emails a day maximum. Is it viable in 2018, or Spamhouse et al has already ruined email to the point, that using big email providers like Google, Protonmail, etc is the only serious option for business?
