I dislike every email client I&#x27;ve used. I dislike Tbird the least.<p>If Tbird doesn&#x27;t survive this transition, I&#x27;ve thought in the past of using something like Mutt, with &lt;something&gt; to display rendered html, and &lt;something else&gt; to compose html mail.<p>And &lt;yet another thing&gt; for calendar access to my fastmail calendar.<p>Any suggestions for any of those things?
