IDLE Command

The IDLE Command

The IDLE feature allows supported IMAP accounts to receive new messages automatically without having to be told to check for messages. This is why you might see messages appear in Postbox very soon after it reaches the server. However, some servers do not support IDLE since the it keeps the connection open by periodically sending a message to tell the server that "I'm listening".

Disabling IDLE

In order to disable the IDLE command for your IMAP account go to the following location:

Mac: Postbox > Preferences > Accounts > [your IMAP account]

Windows Tools > Options > Accounts > [your IMAP account]

  • Click the Advanced button. In the subsequent window, uncheck "Use IDLE command if the server supports it."
