Problems Checking for New Mail Without a Restart


If you are using IMAP and you are finding that Postbox can only check for new messages if the app is restarted, it's possible that your server works better with a smaller number of cached connections.

To change this setting,

  • Go to Options | Preferences > Accounts > [your mail account] > Advanced Button
  • Change the number of cached connections from 5 to 1. Restart Postbox.
