Hello,
I'm trying to setup Cyrus Murder for testing and have three virtual machines
for this purpose (frontend, mupdate and backend). The three machines are
running Centos 6.5, SASL 2.1.23 and Cyrus 2.3.16
Looks like communication from frontend to muptade and from backend to mupdate
is working fine since I can list the mailboxes created in the backend using the
“cyradm -u cyrus localhost” and “lm” commands, which shows the same user’s
mailboxes result on the three boxes.
The problem seems to be between the frontend and the backend since the frontend
is not forwarding the imap requests to the backend. To test this, I am using
the command “telnet localhost 143” on the frontend server. Once that I get
connected and authenticated, I issue the command “select inbox”, but I receive
the message “NO Server(s) unavailable to complete operation”. In the
/usr/log/maillog file there is an error message that says “failed: Connection
timed out”
I have not configured yet the smtp server, not sure if it is required, so I am
trying to focus to get the imap part working.
Any guidance would be appreciated. I have spent several days working in this
problem without getting any progress at all.
Here are my configuration files:
