[SaF] email errors

[sajeev]

Sir/M'm,
Why am I getting the following error while sending a mail to 
the President of USA through my ISP provided email?
I quote :

Your message was not delivered because the destination computer does
not support electronic mail (SMTP). Correct any mistakes in the
address and try sending the message again.

whitehouse.gov doesn't support SMTP mail delivery
The following recipients did not receive this message:
<[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>>


Regards,
Sajeev.
