Currently my imail server v10 face problem to receive email from some sender to some sub-domain.

for example: <somebody@kangean-energy.com> sent a test email to <somebody@candp.com> and <_test@jakarta.candp.com> , <somebody@candp.com> can receive it, but <_test@jakarta.candp.com> cannot.

here @candp.com is a domain with MX record 203.126.181.40

@jakarta.candp.com is a sub-domain with MX record 203.126.181.42 (@indoneisa,candp.com is main domain, jakarta.candp.com is an alias)

this 2 IP is for same server

When sent test mail from yahoo,hotmail,gmail to these two email address, got no problem.

Please HELP, thanks a lot
