Your hosts file is incorrect, look at the message you've already posted here: Failed (2)

You should also search the forums for the relevant error message before posting, look at some of the solutions here: site:zimbra.com site:zimbra.com +"loops back to myself" +solved - Yahoo! Search Results

I don't think it's about host file..

It should be in the same format as the one you've posted in the other thread. Go to the Split DNS article and read the details of what the format should be and how to check your configuration of DNS & hosts file.

OK, if you think it's something else then feel free to search the forums for an answer. Did you bother to look at the link I provided in my last post with solutions in it?
