* "A query for either TXT or A" is a single operation that returns
both records, if they exist, in the same packet. There's no ordering.
* SMTP uses MX, not TXT.
* As an aside, while some broken SMTP implementations use A if they
can't find an MX, but they are not supposed to... if there is no MX
the mail is *supposed* to bounce.
