Looking for feedback re replacing previous Plesk email management on new ServerPilot/DigitalOcean/Ubuntu 18.04
New here, so be gentle! ;-)
We recently migrated 11 WP websites from Vultr/Plesk to ServerPilot/DigitalOcean on Ubuntu 18.04 Droplet. Website migrations were fine, but I didn’t realize that email accounts would be such a gigantic pain in the rear-end!
Could some of you old hands recommend a simple but reliable replacement for Plesk’s email management? We need to set up new business email addresses to replace the current addresses, as quickly as possible. I have read most of the Q&As here, and it looks like our options are:
 Self-host a mail server on a separate Droplet – which would you recommend for ease of use and reliability for a Linux noob? iRedMail and Mail-in-a-Box seem like the most popular solutions.
 Set up something like Plesk (VestaCP, Webmin)on a separate Droplet – which, if any, would you recommend for ease of use and basic features like email management, file management?
 Use a mail forwarding solution – which are the most popular and affordable? Currently looking at Mailgun for a solution here.
 Give up and farm the problem out to someone like Google and let them collect and sell our clients’ personal data? Not really a ‘solution’, but an option, albeit a bad one!
Any thoughts/feedback/solutions greatly appreciated!
