I want one of the domains I manage to have null MX
records: i.e., MX RR
.
I'm trying to figure out how to specify MX RR
under djbdns
, but my searches haven't yielded any information about how to do this.
I did the following for the moment, but I know this isn't the proper way to null out MX
records ...
@example.com:127.0.0.1:a:0
@example.com:127.0.0.1:b:0
... and I'm pretty sure that the following is just as undesirable ...
@example.com:localhost:a:0
@example.com:localhost:b:0
Is there a djbdns
-based syntax for creating MX RR
records?
Thank you in advance for any suggessions.
Per the patience and valuable help from @Nikita-Kipriyanov (see the comments below my original Question), I now see that the following is the answer to my question:
It generates this ...
... which is indeed a suitable Null MX record.
I also tried this ...
... and it also generates the same MX record.
I prefer this second one, because it doesn't deal with any spurious references to
127.0.0.1
, and also, that syntax sort of appears to reference something that might be "Null" in some way, due to the absence of anything except that one dot. It will therefore be clearer to anyone examining my djbdns domain definitions that this is indeed probably a "Null MX" specification.
