Excuse me, I object!
If you do internet mailing in the 21st century you *should* add an MX
record (and use SPF, DKIM and DMARC)
I assume that's just your subjective preference rather than an RFC, or
similar, recommendation?
I strive to aviod my personal prefs. RFC says one thing, the daily
reality is the usage of MX record.
