Filesystem

For single-node installations, Stalwart Mail Server supports storing emails and blobs on the local filesystem. This is done using a hashed directory structure, which is designed to prevent filesystem slowdowns when storing large numbers of files in a single directory.

Configuration​

The following configuration settings are available for the filesystem blob store, which are specified under the store.<name> section of the configuration file:

  • type: Specifies the type of storage, set to "fs" for filesystem storage.
  • path: This option specifies the path to the directory where blobs (e-mail messages, Sieve scripts, etc.) will be stored.
  • depth: This option specifies the number of subdirectories to create. The default value is 2, which means that the directory structure will be two levels deep.

Example​

[store."filesystem"]
type = "fs"
path = "/var/lib/data/blobs"
depth = 2
