problem in sending mail
I have a problem in send mail to a domain.
I have two server setup to compare the performance.
First one FC 5 and Second one on FC 6 X 64bit ( which have been modified accordingly).
Both system are working fine for last two three weeks now. But we found that the FC6 X64 version can not send to a specified domain for somereason. And FC5 have not problem both on the same network with the same configuration.
I found the zimbra.log have the following difference:
This is from FC 5

Any way to fix this problem?
