Press `Quit' to exit without saving. Press `Help' to bring up this help message. In the `Run Controls' panel, you can set the following options that control how fetchmail runs: Poll interval Number of seconds to wait between polls in the background. If zero, fetchmail will run in foreground. Logfile If empty, emit progress and error messages to stderr. Otherwise this gives the name of the files to write to. This field is ignored if the "Log to syslog?" option is on. Idfile If empty, store seen-message IDs in .fetchids under user's home directory. If nonempty, use given file name. Postmaster Who to send multidrop mail to as a last resort if no address can be matched. Normally empty; in this case, fetchmail treats the invoking user as the address of last resort unless that user is root. If that user is root, fetchmail sends to `postmaster'. Bounces to sender? If this option is on (the default) error mail goes to the sender. Otherwise it goes to the postmaster. Send spam bounces? If this option is on, spam bounces are sent to the sender or postmaster (depending on the "Bounces to sender?" option. Otherwise, spam bounces are not sent (the default). Use soft bounces? If this option is on, permanent delivery errors are treated as temporary, i. e. mail is kept on the upstream server. Useful during testing and after configuration changes, and on by default. If this option is off, permanent delivery errors delete undeliverable mail from the upstream. Invisible If false (the default) fetchmail generates a Received line into each message and generates a HELO from the machine it is running on. If true, fetchmail generates no Received line and HELOs as if it were the remote site. 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.
