TSmtp class Problem

[Milan Mehta]

Dear All

I am trying \samples\testsmpt.prg. While trying to send mail

using the tSmtp class, I get following error.

undeliverable to lotusint@sancharnet.in

Server response to MAIL FROM:
550 5.7.1 No Reverse DNS Entry for host: 210.212.142.16 -

authoritative host not found

Can anybody guide me ?

Milan.
