Well, thanks for explaining this. I, too, was very confused by the
apparently "invalid" syntax of yahoo's own DK records. I figured I
was just missing something in the spec since I am *not* an expert on
DK.
I've not checked, but I'm guessing that the same issue hasn't shown up wrt SPF
records? Is that so, Wayne?
I know of no cases where SPF records are escaped by dig, but I could
have missed some. The SPF records syntax doesn't use semi-colons, but
they do use a bunch of other special characters in the set [:=%{}+,-./=_?~].
Domain names can include any visible ascii character other than a
space, so something like "v=spf1 a:;.yahoo.com -all" would be valid,
but I don't think many people have considered using semicolons in a
domain name. When they want to create a domain name that isn't a
valid host name, most people choose to use an underscore. I suspect
that most people wouldn't even think that ;.yahoo.com is a valid
domain name.
