What part of &quot;mail to abuse@ or postmaster@ fails&quot; don&#x27;t you understand?<p>The web-form workflow breaks in many ways: console tools (which I use for email), mobile, and more.<p>The fact that I can simply &quot;bounce&quot; the whole message at Yahoo&#x27;s spamtraps, <i>if they had such a thing</i>, and they can sort the message&#x27;s legitimacy and structure themselves, but they don&#x27;t allow this, speaks volumes.<p>And again, this shit for a decade or more.<p>Now, if Yahoo wanted to creat CLI tools to incorporate into mailflows for those of us who know what we&#x27;re doing to slot into their systems, great.<p>But ultimately, their problems aren&#x27;t mine, I&#x27;ve washed my hands.
