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.
