Hello,
I just installed iRedMail on a brand new CentOS 6.3 server.

For some reason I cannot start clamd, this is affecting incoming and outgoing messages.

When I try to start it I get the following.

[root@mail1-ny tmp]# service clamd restart
Stopping Clam AntiVirus Daemon:                            [FAILED]
Starting Clam AntiVirus Daemon: /bin/bash: line 1:  1597 Killed                  clamd
                                                           [FAILED]

Thanks,
Mike
