Looks like someone may have customized Log4j on your system.

If you reference https://wiki.zimbra.com/wiki/Using_log4 ... xd_Logging . you'll see the commands you need to inventory all of the loggers set for your server and for your mailboxes, as well as the commands necessary to delete the one(s) you don't need.

Hope that helps,
Mark

I wonder if you are hitting Zimbra's built in Denial of Service Filter?

This wiki will show you some steps to take to review your log files and see if the problems you are experiencing are in fact caused by the DoSFilter.

If so, you can edit the settings as shown in the wiki: https://wiki.zimbra.com/wiki/DoSFilter

Also be sure that you are logging the Original IP address to avoid DosFilter false positives. You may need to run:

Code: Select all

zmprov mcf +zimbraMailTrustedIP <local_ip_address_of_your_proxy_server>
zmcontrol restart


Hope that helps,
Mark

Many Thanks you Mark
My problem appears when my users try to reply to emails ( when access web email from out side my company... Not using Private IP) when they are in home or access from other countries
Please see my configuration for Dos in the attachment.
Range ( 192.0.0 , 10.0.0 are private for my company ... 192.0.0 is the DMZ and 10.0.0. is for employees)
No problems for Composing/Replying/Forward from my Lan .
No problems in sending/receiving Locally or from others domains

Hmmm....

Let's start with the basics, just to be sure.

Please post the output from a command prompt on your zimbra server to the following six commands please:

Code: Select all

cat /etc/resolv.conf
cat /etc/hosts
host <the full fqdn of your Zimbra server>
host <the ip address that was given as a result from the previous command>
dig <the primary domain on your Zimbra server> mx
dig <the primary domain on your Zimbra server> txt


All the best,
Mark

Thank you Mr.Mark

My system was up since 5 years..
No problem in sending/receiving from any domains in general
The problem appeared suddenly and randomly when someone from my users ( outside my LAN)try to reply to specific message) in the inbox.
In the same time no problem for composing new email for that user.. and no problem for replying to another emails
