Question : Email Reject using google hosting

HI, i'm recently using google applications and this tool give me a free email hosting.
i set it like the tutorial:

Priority HostName     Goes To Address (Mail Server)      TTL Value
10         @                 ASPMX.L.GOOGLE.COM.              1 week
20         @                 ALT1.ASPMX.L.GOOGLE.COM.    1 week
30         @                 ALT2.ASPMX.L.GOOGLE.COM.    1 week
40         @                 ASPMX2.GOOGLEMAIL.COM.       1 week
50         @                 ASPMX3.GOOGLEMAIL.COM.       1 week

but in my A hosting i have this:
Host       Point to
@          72.167.131.40    (this is other server where i'm hosting my webpage)

the question is when i send email from gmail i receive this 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. The error that the other server returned was: 550 550 sorry, mail to that recipient is not accepted (#5.7.1) (state 14).


and when i send emails from other emails i receive it sometimes good and other time i don't receive the email
and i receive this error:
64.202.166.12 does not like recipient.
Remote host said: 550 sorry, mail to that recipient is not accepted (#5.7.1) Giving up on 64.202.166.12.

any ideas?

thanks a lot
Gustavo
