SPF/DMARC/DKIM make this all a bit more complicated now. There are plenty of MTAs out there that will refuse to send you mail if it's not all correct.

This is absolutely not difficult to get right. Run OpenDKIM and OpenDMARC on your server along with your email stack (I use Postfix and Dovecot). Use a tool such as mail-tester.com to verify compliance.
