Yahoo Mail’s spam filtering needs to become more reliable. A particularly serious problem is that legitimate emails are sometimes incorrectly sent to the Spam folder. This means users can miss important messages because they cannot confidently rely on the Spam folder to contain only unwanted mail.

At the same time, users dealing with persistent spam and scam campaigns need better tools to control what reaches their mailbox. Yahoo should allow all users to block an unlimited number of sender domains, rather than imposing a very small limit.

Better spam filtering combined with unlimited domain blocking would give users much more control over their mailbox and reduce the risk of important legitimate emails being buried among unwanted messages.

For users who have accumulated an email address over many years, changing their address simply because spam filtering is unreliable is not a reasonable solution. Yahoo should provide the tools needed to keep an existing mailbox clean and trustworthy.
