Error "Technical details of permanent failure..."

[Zariah]

I don't whats wrong with my email account.I can send emails but I can't receive them. I get the following error:-

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient
domain. We recommend contacting the other email provider for further
information about the cause of this error.

I guess it is is coming from Postfix. Please help.

I think gmail stinks and it is time to go to yahoo to return. Yahoo has a limit per hour, however, no e-mail get bounced. Google started free e-mail service once when she and millions of people and small businesses who depend on their services were to be hooked, they started this game of filtering, blocking and delaying our e-mail. However i am not a Postfix expert but I tried setting up an account, and it worked fine.I use one main mailbox and /etc/postfix/aliases
