I have made repeated changes to the interval (300 seconds, 180 seconds, 120 seconds, 60 seconds) with service fetchmail restart issued after each change, but the polling interval remains at 900 seconds.

Thus, it appears that when the daemon starts, it correctly loads the configuration from the fetchmailrc file (since it pulls emails according to the config) but subsequently overrides the polling interval with the setting in /rc.d/fetchmail.

The fetchmail manual page states that command-line options override
configuration file defaults. The startup script for the fetchmail
service must pass -d to make sure that fetchmail starts in daemon mode,
and since -d requires an argument, the startup script must pass one -
and it uses the value from its own config file. Thus, whatever you put
in the fetchmail config file will be silently ignored.

G'luck,
Peter
