Surely if the MX record is declared as a . then the preference is
irrelevant?

I noticed inconsistencies in how domains are publishing null MX records. In
RFC7505 it states these records should be published with a preference number 0.
I am seeing a variety of preferences specified though.
Example:
;; QUESTION SECTION:
;hotmai.com. IN MX
;; ANSWER SECTION:
hotmai.com. 2530 IN MX 10 .
Is anyone ignoring the preference number in their implementation?
Thanks,
Brian
