[BlueOnyx:12451] Re: More info:user unknown problems

[Roy Urick]

After further testing, it gets stranger.

-The server hostname is blueonyx.domain.com.
-the vsite that contains the users is onyx.domain.com.

-the virtusertable refers to the site users properly: (e.g. 
roy.urick at onyx.domain.com    rurick)
-I can send mail to any new user aliases I create from today forward, 
but any users created weeks ago wont flow with the 511 error below.  I 
dont see any difference in the virtusertable file between the new and 
the old entries.
-If I create a new alias for an existing user (that is otherwise 
failing), the brand new alias works, but the old does not. No prior 
aliases and I can only send to username at blueonyx.domain.com.
-If I delete/save/recreate an alias, it starts working. no perceptible 
changes appear in the virtusertable file.
-If I create an alias that is the same as the username it saves in the 
GUI OK and appears if I close/reopen the user account. It doesnt get 
added in the virtusertable and I cannot deliver mail to that ailas. (The 
brand new accounts I created today DO show the alias that matches the 
username properly. Only the prior accounts behave this way)
-I can send to admin at blueonyx.domain.com but not admin at onyx.domain.com 
or admin at domain.com. things like yum update reports bounce when trying 
to send to "admin" (its using admin at onyx.domain.com).

Hopefully the above details will help shed some light on the issue.
