Please provide the feature to block particular domain so that spam mail from that domain can be blocked
Yahoo Mail Plus lets you block up to 500 domains while your subscription is active. Block domains by using the Settings view in Yahoo Mail. Once you block a domain you will also be unsubscribed from the brand.

Why is it that in "Security and privacy" we can't have conditional fields, such as block all email addresses that contain ______? This exists under Filters, but spam would be more easily addressed under blocked addresses, plus there are 1,000 permitted there as opposed to FIlters, which permits only 500. The problem is that spammers use random letters in parts of their email, like firstname.lastname@example.org . Using blocked addresses that require the full email, such as one like this example, is futile. Yes, it will block that particular one, but there will be endless others with a random mix of letters and just the dailyupdatestoday.com extension.
