Solution 3: Check if the Recipient is no longer valid
If the person to whom you are trying to send an email is no longer available at the same email address, Yahoo will consider an invalid recipient. Moreover, this can happen when you are using an incorrect or older email address. Additionally, if the recipient has deleted his/her email account, Yahoo won’t be able to send your message.
Solution 4: Refrain from sending Offensive or Illegal Content
Yahoo is quite strict about its policies against illegal and offensive content.

From spam or promotional emails, nudity, abusive language, inappropriate media attachment including audio and video, hate speech, pornographic content, to duplicate emails, all such content is referred to as offensive and illegal content.
