Find from logs

[tiarra]

Hi all

I have configured my zimbra account in Gmail as pop3.
So when i fetch zimbra mails using Gmail- How can i find the client IP. In the log, could find it specifying the gmail IP and not the client PC IP Which would help me trace the actual person..

For eg.. My pc IP is 1.2.3.4 and gmail IP is 203.x.x.x and account in zimbra is abc@domain.com
I fetch abc@domain.com mails fromgmail from the PC with IP 1.2.3.4

I can find 203.x.x.x in the logs ngnix.log trying to accees abc@domain.com; but 1.2.3.4 is not specified.
I dont know if i have missed any logs
Can anyone please help...

Check /opt/zimbra/log/mailbox.log.

Thanks but i could not find anything to provide me the actual client IP..It shows that user accessing external account but my concern with IP still is not cleared.

another question is suppose i have a user has masked his IP, then targetting him is difficult isnt it?

Well if they mask their IP then it would be difficult anyway ... These are security questions not just related to Zimbra but networking in general.
