Re: MX and TXT

2004-01-12 22:02:32


As I mentioned previously, I don't use BIND
so I don't know how to add a TXT record to an MX lookup,
but it cannot be difficult and isn't disallowed.

I think the BIND example before looked like this:


    mx.example.com.   A    10.9.8.7
                      TXT  "v=spf mx -all"

Now reading it that way, it may look like the 'mx.example.com'
has two pieces, an A and TXT "in one piece".  But the above
BIND zone snippet is equivalent to

    mx.example.com.   A    10.9.8.7
    mx.example.com.   TXT  "v=spf mx -all"

or even

    mx.example.com.     A    10.9.8.7
    blah.example.com.   A    127.0.0.1
    mx.example.com.     TXT  "v=spf mx -all"


You've created two separate types of records for mx.example.com,
an A record and a TXT record.  The first example does use the
shorthand of not explicitly naming the hostname itself, but it's
still a completely separate record.

Hopefully this clarifies some of the confusion.
