Thunderbird is the only FOSS mail client that I managed to set up yahoo mail and gmail addresses in less than a minute. If you mail provider requires an in browser athorizaton, you are just taken there. No fuss, which is why I use it. Actually I never managed to make those addresses work with either Geary, Evolution or Kmail. On the other hand the UX/UI is quite bad. Just try it out, you'll see what I mean.
