On my system (OMV & debian on a HP Gen8 Microserver) I had a lot of postfix and bounce processes running and over time they slowed down my system a lot by causing a lot of iowait. I stopped the postfix service and the problem was gone. see below.
So my questions are:
Does OMV need postfix? Or can i safely disable / uninstall postfix? I don not want an SMTP Server running on my NAS if I don't have to.
For notifications i use an external SMTP-Server Server.
did anyone else experience similar problems or was that just me?
Is there a problem with the installation image? Why is postfix installed and running in the first place?
Thanks and keep up the good work!
