Are Yahoo email addresses a viable alternative to Gmails in regards to forwarding and setting up an autoresponder?
Gmail is the best.... Even when there is some deep sea cable problem.... Only Google a.k.a gmail is up... Yahoo and the rest are all drowned..
Gmail is better when it comes to features like what you ask for. Even setting up basic POP access to your Yahoo account requires you to pay. Yahoo may give you unlimited space, but it's not worth it compared to the other features.
