Mail Retrieval

The Mail Retrieval package can conveniently retrieve mail from other servers allowing the centralization of e-mail on a single ClearOS server.


If you did not select this module to be included during the installation process, you must first install the module.

You can find this feature in the menu system at the following location:



Any number of servers can be added to the mail retrieval list using the “Add Entry” form. The interval polling time can be configured from 1 minute up to 3 hours.

  • Server - The server name. For example,
  • Protocol - The server protocol. Currently, POP3, IMAP and APOP protocols are supported. If you do not know the protocol, you can have the system auto-detect by selecting 'auto'.
  • Username - This is the username on the source server.
  • Password - This is the password on the source server.
  • Local User - This is the username of a mail account configured to receive mail on the server you are configuring.
  • Keep On Server - Enable this checkbox to leave a copy of the mail on the server.
  • Active - Enable this checkbox to start polling the remote server for mail to fetch.


Have a look at the system logs if you are having problems. The mail retrieval system (fetchmail) logs information to /var/log/maillog. Ignore any entries you see similar to:
