Can you give an example in BIND zone file format of what you mean by
"add a TXT to the MX record"?
Yes and no. I have to confess that I don't use Bind to serve these records.
(One rainy Saturday I added DNS to a Java server I had written! Did mail too
which explains the ips in the following entry!). Below is
an MX generated by dnsstuff.com to illustrate what I mean by a TXT
record in MX.
I found it so much easier to teach my smtp to check this than to check for a
separate TXT record. But perhaps this is too nonstandard.
