Unfortunately, even though I would very much like to abandon mine (even though it's used only for some spammy registrations), email forwarding is not possible unless you pay them, which is obviously out of question.

So basically, the best I can do is start changing my associated email address at the services I care about that are still using my yahoo email address. After a while, my yahoo inbox will be 100% spam (as opposed to 90% spam now), so I'd be able to move on.

Some email services will allow you to "fetch" mail from another service. For example, I think it's possible with gmail to configure it to log in periodically to your yahoo account and fetch the email.

I run a hosting business and our email stack supports this feature. We use a combination of open source technologies to transfer email like imapsync for the initial transfer and then use a glorified version of fetchmail in a cron job.
