I have a goal of securing email. Updated the company mail server and DNS (CentOS 7 + Postfix, otherwise pretty stock) with support for SPF, DKIM, and DMARC. So far, all good, and everything "just works". Our mail server has supported SMTP / TLS for a long time, but recently I've been considering requring TLS all the time. Is there anybody here who's done this? Has it caused any particular fallout? I'm curious about: 1) Requiring SMTP / TLS for any inbound email. 2) Requiring SMTP / TLS for any outbound email.
