Poll interval
        Number of seconds to wait between polls in the background.

Logfile
        If empty, emit progress and error messages to stderr.

In the `Remote Mail Configurations' panel, you can:

1. Enter the name of a new remote mail server you want fetchmail to query.

To do this, simply enter a label for the poll configuration in the
`New Server:' box.  The label should be a DNS name of the server (unless
you are using ssh or some other tunneling method and will fill in the `via'
option on the site configuration screen).

2. Change the configuration of an existing site.

To do this, find the site's label in the listbox and double-click it.
This will take you to a site configuration dialogue.
