What also if I would lyk to distribute different apps per systems. mail - 1 server, pop - 1 server, db - 1 server, webmail/postfixadmin 1 -server.
You can set value to 'DONE' in 'iRedMail-x.y.z/.iRedMail.installation.status', so that it can skip some steps. it's useful to skip installing components you don't need.
And, maybe you should change some variables in iRedMail-x.y.z/*, such as IMAP server adderss, pysieved bind address, mysql bind address, etc. don't forget to change your iptable rules.
What do the pysieved do again? I just want to clear it and where will I put it on my cluster.
Why not google first? don't be a lazy man.
How do I solve this error in horde when applying Filter Rules (vacation, whitelist, blacklist and etc) ?
"Error There was an error activating the script. The driver said: "Authentication failed""
