10.6.8 server on Mac Mini

doing DNS, AFP, Mail, iCal, OD for 8 users

 

Clients are all 10.6.8 on Mac Mini

 

Mail is IMAP

Mail is well behaved 98% of the time

But sometimes, on a client, when I try and move a message fro mmy inbox to another mailbox, it says "the message coudl not be moved to mailbox xxxxx"

If I try again immediately afterwards, it always works

 

So I doubt it is anything like a corrupt envelope index, because that would result in persistant problems.

 

It's as if the mail server isn't listening momentarily.

 

 

This is a fairly fresh build of the OS from DVD.  Previous build did exactly the same ting.

 

 

Woudl be very grateful for any ideas.


Mac mini (Late 2009), OS X Server, 10.6.8

    Well, check your DNS services for starters.  DNS errors and timeouts can cause weird and transient errors.  If you're on a NAT'd local area network as is typical, make sure you have no references to any ISP DNS servers; no references to any DNS servers off of your LAN.

    Thank you for your reply.

     

    Yes we are on a NAT'd LAN.

     

    Client DNS is solely the local server

     

    Server DNS service only provides our one local domain, has forwarder adresses set to 8.8.8.8 and 8.8.4.4 (Google).

     

    I am not confident, but I don't *think* this is the problem because DNS takes some time to timeout (15s?) and the error message above comes up almost instamntaneously.  ie too quick to be a DNS timeout.

     

    If it was a DNS problem, what would I see in which log?  named.log on the server is empty. 

    I'm not sure what to look for in logs on the client?

     

    Thank for any further ideas.

    To verify the server DNS, launch Terminal.app from Applications > Utilities on the OS X Server box and issue the non-destructive diagnostic command:

     

    sudo changeip -checkhostname

     

    The clients would have references only to your local DNS server(s), visible via the client Network Preferences settings.  (These DNS server settings are usually either hard-set in the client, or acquired from DHCP by the client.)

     

    You'll want to use Console.app or direct access to the /var/log directory (on the server), and see what gets logged when the mail message move operation fails.

     

    As a preemptive operation, I'd also rebuild the mailboxes involved (on the client(s) involved).  I've seen a few mailbox corruptions over the years, but not one that caused this behavior.

    Thanks.

     

    changeip returned "The names match.  There is nothing to change".  So all OK there.

     

    I will rebuild the mailboxes as you suggest.

     

    And I'll wait for it to go wrong and loook at the log.  May take a week or 2.
