Hi Tug, The answer depends a lot on what do you want e-mail server for. If all you want is just a reliable e-mail service, I would look at Proton Mail or malibox.org. If you want, let's say, better spam filter, the combination of dovecot/spamassassin/fetchmail with mentioned earlier mail services could be an option. Just my two cents. Regards, /Dmitriy.
