Hi

"sa...@pibsatelite.org.mx
550-No Such User Here "

You need to check with "pibsatelite.org.mx" that the user "sarai" has
a valid mail box.

Doesn't look like a problem at Google' end

Regards

Hi, well the last week when i dont configure Postini I can send and receive mails from this domain, so when I configure my postini, I get this error.

you need to check if its a valid mailbox and also check for typo.
