YPOPS is the only option that you can try to get pop3 access for a free Yahoo Mail account. It does not work for all people. Even if you get it working it has a way of eventually breaking. If you want to try the YPOPS setup again here is our guide for getting it configured :
I know this isn't relevant to BigD31 who obviously already has a Yahoo account (presumably at "yahoo.com"), but, just for clarification, I was under the impression that Yahoo's other domains (e.g. ymail.com) and their other international locations (e.g. yahoo.ca, yahoo.au) allow for free POP access. I have never tried these myself (and cant', since I no longer have any Yahoo accounts), but I do remember reading something to this effect.
