I fully agree with most of the former, except for the Google part. Google is to privacy what a shark pool is to a carp. If possible, avoid Google at all cost, and particularly for E-Mail. There are services around that cost a very small amount of money (e.g. mailbox.org or posteo.de), provide a very reasonable service and do *not* peek into your mail for advertisement targets and sell your data to their customers. If you want to run your own mail server (there are good reasons to do so, I've been running my own services for many years now) be prepared for a learning curve, as mail is not as simple and straightforward as it looks. You should also run your own DNS in that case, as many modern features of secure mail services are tightly linked to DNS (e.g. SPF, DKIM, DMARC etc.). DNSsec is preferred. There are some good books around (e.g. the Postfix/Dovecot books by Peer Heinlein, who incidentally is the owner of the mailbox.org service, but the Postfix book only seems to be available in German). Without a good foundation on running mail servers and/or some help from experienced mail server operators you're almost certain to screw up big time, which in most cases means ending up on some blacklists or having mail delivered very unreliably. As for the software question, I recommend the Postfix/Dovecot setup, enriched with some additional components to support graylisting, virus checking, spam filtering, DKIM, DMARC and SPF. Pete.
