Reference: Yahoo Email Domains

Sometimes it comes in handy to know all of the common domains associated with a given Internet Service Provider (ISP) or webmail provider.

I believe these are all of the most common email domains associated with Yahoo! Mail, according to what I can recall, with help from this Port25 forum post.

Yahoo Domains:
yahoo.com
ymail.com
rocketmail.com
yahoo.co.uk
yahoo.fr
yahoo.com.br
yahoo.co.in
