I have post any other link before reading this read timeout issues. I have been search througth the wiki and other means to fine a solution on this but could not fine any answer and solution. try to disable the DNS lookup etc..
no luck at all. Can you help?
Here is the case, the I have a friend using a exchange for his company email domain. Only one domain on the server.
And we are using zimbra, 4.5.7 now.
And zimbra log show read timeout, and could not delivery the email just for this ip machine for some reason. And I believe it is something to do with the postfix configuration as he had another party using the postfix have the same problem.
Therefore, I set up any other machine just to locate the problem but that machine using zimbra 4.5.6 FC5 did go throught.
I have compared the setting on two machines, only different is that
one is the FC6 64 bit ( problem one)
one is the FC5 32 bit ( no problem one)
all the postfix setting are the same, I have compared them side by side.
here are the log, any solution?
