Hello, I have been running into an issue of our email server, Our email is filling up the server, and we want to find away to store the email some place so that our server does not keep filling up. The idea we had in mind was to store them separately on a NAS, or some other storage device. Thanks for any ideas of how to manage the ever growing issue of email. Joseph
Yes, you can do that. All email is stored in /var/vmail, just move the email on your NAS and then mount /var/vmail from NAS via NFS. Just take care to stop postfix and dovecot before doing this.
Depending on the size of your setup either setup the NAS with NFS and check out https://doc.dovecot.org/configuration_manual/nfs/ as described by till or if we're talking about a virtual machine, create a seperate disk and mount it to /var/ when using LVM you can add multiple disks over time if you have a speific limit depending on your storage solution that you're using in your hypervisor setup.
