Hello,

Per our documentation:

  • The maildir format uses flat files, which cause systems with large mail archives to exhaust their inode resources quickly.
  • The mdbox format stores multiple messages in a file and uses a simpler indexing scheme. This format requires fewer files, reduces inode usage significantly, and decreases disk space usage.
Thus, I recommend reaching out to R1Soft directly for information about how their product will interact with change to how the messages are stored with mdbox.

Thank you.
