Dear sir:

I have config mutli server environmenmnet 1X MTA 1X Mailstore 1X LDAP in subnet 10.10.9.8 MX record config and canbe resolvd DNS.

send out is fine but send in there is error. I got anohter zimbra server in 10.10.10.8.0 it is successul to receive email from 10.10.10..8.

I got a mil server in another subnet e.g. 10.10.10.8 , when trying to send to the zimbra server it occur.

reason Error transferring to zim.zimbra.COM; SMTP Protocol Returned a Permanent Error 554 5.7.1 <a@zimbra.com>: Recipient address rejected: Access denied


I already read most on web, set MTA trust network even postfix mynetwork added all subnet in ...10.10.9.0/24 and 10.10.10.0/24 but still fail..

in maillog: it always say TLS connection established from unknown[xx.xx.xx.xx]: SSLv3 with cipher RC4-MD5 (128/128 bits)
but receipt reject ( tried alresdy disable TLS or authorzation)

any idea ?
