Yahoo seems to incorrectly return catch_all=true and deliverable=false

[stephennancekivell]

Hi, The results for yahoo seem to be incorrect.

I get this result for valid yahoo addresses.

{"host_exists":true,"full_inbox":false,"catch_all":true,"deliverable":false,"disabled":false}

If I try and email a random yahoo email like the ones used for catch_all detection, I receive a bounce back.

It seems like SMTP RCPT verification is not enough for yahoo and possibly other providers.

Perhaps this project could maintain a list of providers that don't work and return an 'unknown' response.

Ps, thanks for the nice project.
