Things to check:
1) Are you specifying the FULL email address, including domain? Yahoo requires this.
2) Try “localhost” instead of “127.0.0.1”; ISTR some problems with that.
I’m suspicious that this flat out may not be possible. Yahoo requires SPA (Secure Password Authentication https://en.wikipedia.org/wiki/Secure_Password_Authentication ), apparently, and Eudora doesn’t appear to support that.

I have pared down the config file to the bare essentials, dealing with Yahoo only, and still get the error message about username and password being not recognized. I have tested these via browser access to my Yahoo server, and found them to be correct. Does anyone have any further suggestions please?
