NOTE: Fetchyahoo will only work if you have selected the all-new Yahoo web interface as your default. You can find out how to switch to the new Yahoo here.
Installing and using FetchYahoo:
* Download the package and uncompress it : tar -xvzf fetchyahoo-x.y.tar.gz
* cd fetchyahoo-x.y ; chmod a+rx fetchyahoo
* Edit fetchyahoo
OR copy fetchyahoorc to /etc/fetchyahoorc or ~/.fetchyahoorc and edit that
OR just run fetchyahoo from the commandline
(use --help to see all options).
* Use your mail client to get mail from your spool or mbox file.
Options specified on the commandline take precedence over options specified in the configuration file, which in turn take precedence over ons hardcoded within the fetchyahoo program file.
