Tips on cleaning up disk space


Although Xeams does not take a lot of disk space when you first start using, it can potentially take a large chunk on your disk after a few years. This article talks about how to clean up disk space that is no longer needed.

  1. Ensure messages are not retained indefinitely. This is done by going into Server Configuration → Message Retention and ensure none of the values are set to -1, which means files will never be deleted.

  2. Second, if you're not using the IMAP/POP3 servers in Xeams, ensure the server type is not Hybrid. Switch it to Firewall mode instead. This is done by going into Server Configuration and checking the value for Server Type.

    Xeams will maintain user repositories for every user in the $INSTALL_DIR/UserRepository folder when the server mode is either set to Stand-Alone or Hybrid. This folder can grow very big if user repositories are maintained but no user ever connects to it to fetch and delete messages.

    You can safely delete the $INSTALL_DIR/UserRepository if Xeams was incorrectly configured to run in Hybrid mode and no one is using IMAP/POP3.

    User Repositories will always exist when running Xeams in Stand-Alone mode since you will have to enable IMAP/POP3 for users to get their emails.

Viewing Disk Usage

Most disk space in Xeams is consumed by the following folders:

  • Global Email Repository - Every incoming email is stored in these folders and is used for archiving. When you search for a message you received six months ago, this is where the data comes from. This repository is further divided into the following three folders:
    1. $INSTALL_DIR\GoodEmails - Holds Good messages
    2. $INSTALL_DIR\PossibleSpam - Holds Possible Spam messages
    3. $INSTALL_DIR\SpamEmails - Hold Spam messages
  • User Repository - Files stored in this location are saved for every user and serve data for POP3 and IMAP clients.
  • Search Indexes - Files in these folders contain indexes that make email searches faster.

The easiest way to view the disk usage for these folder is to click the magnifying glass icon, as shown in the image below.
