My feeling is that this is beyond what we can successfully
recommend in a BCP.
The BCP would reccomend the e-mail address of the local
administrator. The software vendor still needs to pick a sensible
default. I was trying to cook up something for the latter.
fields. So the draft suggests the mname to contain the 'local'
administrator (SHOULD) and the vendor puts its own default. (It is
unfortunate that such address will become a spam magnet).
It would also be a spam reflector and open a can of worms IMHO.
Agreed, on the other hand the vendor could also send all mails
received at that address to the bit-bucket.
I wonder if those people clever enough to dig out the RNAME really
would need the help of an auto responder. My point about avoiding
the "."
was more to say "." != "no address" (waiting for someone to point
me to the
existing (bad) precedent).
In the spirit of "Text Dude" here is my try on phrasing this in RFC
speak:
Implementations SHOULD provide a mechanism to set the value of the
SOA RNAME to contain a local contact. Implementations MAY default
this value to "." or, alternatively, MAY configure a mail addressed
maintained by the vendor. No address records need to be provided for
the name server.
(If this is not seen as an improvement I do consent with the original
text)
and while we are at that paragraph. It currently reads:
If using empty zones one should not use the same NS and SOA records
as used on the public Internet servers as that will make it
harder to
detect leakage from the public Internet servers.
Should that first "should" not be a "SHOULD"?
