fetching yahoo mail

[emacsnews]

Hi,
   I'm sure this is very simple but I can't get it to work.
   I just want to read my yahoo mail in gnus.
   I have my gmail set up OK, using offlineimap and dovecot, but I also
   want to read my yahoo mail.
   I couldn't find any secondary-select-method for pop so I added the
   following line to my .gnus.el:
   
(setq mail-sources '((pop :server "pop.mail.yahoo.com" :port 110 :user
"?" :password "?")))

    Do I need to install fetchmail or some other software to pull the
    mail from yahoo, or should gnus do this itself by default?
