Hello,
I have been running my email server (mailcow) on a hosted VPS for years without any problem.
As the storage size of VPS is limited, I move old emails to a VM on Unraid running only IMAP server. This works. However, as VM is running in cache disk, I cannot grow the disk size of VM as much as I want as the cache capacity is also limited.
I would like to use an Unraid share as the storage of mails. What is my best option? IMAP server as docker on Unraid using Unraid share as mounted volume? Mounted Unraid share to VM?
Thank you for your help.
