Maybe I have a solution for you.
Just check for an NS-Entry for the domain. This way you know if
the domains exists or not.
How I would do it?
I sended a resolv-unit to the units-list. I would then double the
function Sys2_GetMXAddr (tz:ShortString):ShortString;
to make a getnsaddr and you have a result.

Are you trying to program a spam-blocker or something like that?
If yes, I would be interested in helping.

Michael.
