local mailbox %s wrong in mailbox list in cyrus 2.3.15

[karen turner]

Hi

Has anyone else had this message in their cyrus logs?

Mar 23 14:56:41 zysv01 mupdate[19515]: local mailbox user.zykdt0 wrong in 
mailbox list

I have identified the section of code that does it.  It's the master mupdate 
server synchronization. It is checking for a ! on a local mailbox line of the 
murder database.

What is the purpose of it checking for a ! on a local mail box line?  
A ! is used as a separator, when specifying a remote server, when its a remote 
mailbox.

We run a unified murder configuration.
I checked and the same code is in 2.3.16 as well.

Cheers
  Karen
