Multi Proxy - mail client failed

Postby thonglm » Sun Oct 02, 2016 5:56 pm

Hi all,

My system Zimbra 8.6.0 U7 on RHEL 6.4:

Server1: Ldap/store/apache/logger/snmp (they are all uses normal ports-http/imap/pop - Mailmode:http;)
Server2: mta/snmp/proxy (the upstream proxy use http - zimbraReverseProxySSLToUpstreamEnabled FALSE; proxymode mixed;)
It works fine!

I added Server3 (to share proxy loading and use one more mta relay), exactly the same with Server2.

Everything is fine, except the mail client. I cann't send by any mail client (pops/imaps is ok). It says smtp authentication error.

On server2: zimbraMtaAuthURL: https://<server1>:443/service/soap/ (I don't know why it works!)
On server3: zimbraMtaAuthURL: https://<server1>:443/service/soap/
The server3 ip was addded to zimbraHttpThrottleSafeIPs.

When using the Server3 to send mail, the log:

Code: Select all

I think I found the problem, there's a firewall missed.

Sorry admin, I cann't delete this post.
