The current version (2.14.7) does not work anymore due to changes on Yahoo's side: Just changed the version number. Compile and runtime testesd. One additional workaround may be needed from some users: Users must uncheck "Turn on SSL" in Yahoo! Mail Options for it to work.
fetchyahoo has been deprecated by the author. It been mostly nonfunctional since Spring 2013 and completely nonfunctional since mid-June of 2013 due to changes in Yahoo's webmail interface. Futhermore it is no longer needed anyway, as Yahoo has free IMAP Per the author: "Fetchyahoo has been deprecated. Use fetchmail instead. The original intention of fetchyahoo was to replace fetchmail for Yahoo! Mail since the free Yahoo! Mail supported neither POP nor IMAP. But Yahoo! Mail now supports IMAP so using fetchmail or standard mail clients is now possible and fetchyahoo is no longer necessary." Its time to treeclean this sucker.
