Thanks for reply Kevin.
I did fear so.
vsnl.net is having clients in range of 100s of thousands, and I they won't
entertain my request.
So I will have to stop using vsnl.net address.
Only if there was a way to specify particular allowed from addresses though,
(instead of domains)!!
Well, any how, nothing can be done and let us hope the SPF business really
makes the world spam free.
