Setting

Description

Use alternate welcome message

This is the welcome message which is displayed to email clients connecting to the service. 

Inactivity timeout

Set the inactivity timeout for the POP service.  If a connection is inactive for longer than the timeout period (in seconds) then the connection will be closed.

Allow concurrent mailbox access

By default POP servers only allow one connection to a mailbox at any time. Enabling this will allow multiple connections to the same mailbox. Be aware that some POP email clients expect they are the only connection to a mailbox and may produce warning or error messages if another connection deletes email during the connection
