Getting error when mailing to gmail/yahoo from specific mail id in my shared zimbra mail server for a particular mail id of a domain, other mail id's in that domain (tgccb.co.in) not getting any issue while delivering mail to gmail/yahoo id's and have checked my mail server IP also and it is not blacklisted though SenderScore report is around 92, getting error message like below :-

I came accross a thread in this forum and was asked to run some commands, like
$ zmprov gs `zmhostname` | grep -i httpdosfilter
$ zmprov gs `zmhostname` | grep -i safeips
--> You can change this values, i need to know the format, and who the ips belong, not the IPs itself.
$ zmprov gs `zmhostname` | grep -i invalidlogin
$ zmprov gas
$ zmprov gs `zmhostname` | grep -i serviceenabled
$ zmprov gs `zmhostname` | grep -i trustedip
--> Again, you may change this values, i only need to know the format and who the ips belong, not the IPs itself.
$ zmlocalconfig | grep -i originating

Below are the output most of whic is blank
