Does that mean we shouldn&amp;#x27;t do it?&lt;p&gt;Apparently, yes.  15 years later, there have been no substantive changes to SMTP.&lt;p&gt;Repeat after me, SMTP is perfect.  It&amp;#x27;s perfect!  Well, there are a few known issues.  But it&amp;#x27;s deployed!  It&amp;#x27;s too hard to change.  You&amp;#x27;re trying to change it?  You&amp;#x27;re a terrible person who doesn&amp;#x27;t understand SMTP.&lt;p&gt;I got that for 5 years before giving up and going to more productive lines of work.</text><parent_chain><item><author>cm2187</author><text>The problem is not so much the attitude of the big guys.
