Does anyone know how to use dig or some other tool to query for TXT records
in DNS?
I'm working on implementing spf on a small domain that I maintain, and it
doesn't seem to be working (according to the validators I'm using.) I'd
like to be able to query the dns server myself, but I can't seem to find
anything on how to extract or view TXT records for a domain.
I tried dig @server domain TXT and dig @server domain MX, but I don't get
the TXT record.
%dig @what_ever_nameserver example.com txt
works for me. Let's see what AOL returns:
%dig @localhost aol.com txt
...

Ummm...this turned out to be an ID10t problem. I'm too embarrassed to explain
exactly what. :-(
But thanks for the explanation. :-)
