we have Network GA 3.0.1_160 and I was trying the zmmsgtrace command but no results so far, always 0 messages found, I tried with this for example:

[zimbra@store1 ~]$ zmmsgtrace -s agms@xxx.edu -r agms3@xxx.edu
-t 20062702
Tracing messages
from agms@xxx.edu
to agms3@xxx.edu
During 20062702

0 messages found

And I'm sure the message was sent and received because I sent it.
I typed it in my store1 server where I have the logger running (only server which has it running)

any suggestions ?
