hi all,


I'm running 2 mac mini servers, one a PDC SL 10.6.8 and the other mail/ichat services again 10.6.8.


DNS is all configured correctly.


Issue: randomly across windows/mac/iphone/ipad mail cleints the end user receives "mail could not be received at this time. the server rejected your username and password etc etc please go have lunch and come back and try again."


i cannot find any pattern to this issue. Where for the same user it works on his ipad, it wont auth on his mac.


Generally some users will go for weeks without a hitch then randomly they will get auth failed for a small period of time.


of note, when this happen to me on my mac, i did a tcpdump and could see that the mail app wasn't even connecting out however i dont think that is the issue generally.


I'm resonably skilled in the sysadmin space and yet have being unable to find the cause, esp given its so random.


in the logs when a user fails, there is sometime a successful auth entry, other times there isn't, and sometimes although rarer, there is a failed auth and ater 6 tries subsequent account lockout.


has anyone else seen this?


I was thinking of upgrading to ML for both servers in the vain hope that it would cure the problem but that seems to be a bit like a sledgehammer ( one that might bring other issues)



macbook pro, Mac OS X (10.6.6)

    I am dealing with this issue right now, and was wondering if you've tried excluding items from TM, instead of disabling.
