Hi list, I'm trying to add an existing cyrus-imap server (additional backend) to an existing cyrus-murder. Unfortunatelly I've run into a wall and the only error messages I'm getting are: cyrus/lmtpunix[8569]: kick_mupdate: can't connect to target: No such file or directory When I try to run: "ctl_mboxlist -mw" it returns: "couldn't connect to mupdate server" and this appears in my maillog: "cyrus/ctl_mboxlist[9125]: connect(mupdateserver.domain.com) failed: Invalid argument" I have no idea where the invalid argument could be as I've compared imapd.conf and cyrus.conf to the existing back ends, and everything appears to be in place. I've also confirmed that the various paths are accurate and the cyrus user has necessary permissions. I've also run mupdatetest, successfully. cyrus@back_end$ mupdatetest mupdateserver.domain.com S: * AUTH "CRAM-MD5" "PLAIN" S: * STARTTLS S: * PARTIAL-UPDATE S: * OK MUPDATE "mupdateserver.domain.com" "Cyrus Murder" "v2.3.7-Invoca-RPM-2.3.7-2.el5" "(master)" C: A01 AUTHENTICATE "CRAM-MD5" S: PDM1NTIwOTI4Ni4xNDY2MzM3MEBuanJoLWVtbDUxMC5meHNlcnZlci5jb20+ Please enter your password: C: Y3lydXMgMzg1ZTYyNTE0Nzc5YmI1ZGRlYWI1Nzk2MGJmNmMxY2M= S: A01 OK "Authenticated" Authenticated.
