Funny I should see this today, I spent yesterday afternoon reading articles about Thunderbird and other mail clients and ended up migrating from Thunderbird to mu4e [0] (purely for reasons of usability).<p>If this is true (and there is some reason to doubt it, as this isn&#x27;t the first time Thunderbird has been declared &quot;dead&quot;), and considering that Geary is no longer in active development either (maybe the Elementary OS guys picked it up?), Mailpile [1] might have a chance to fill that gap. Other than that, there&#x27;s always Claws Mail [2].<p>[0] <a href="http:&#x2F;&#x2F;www.djcbsoftware.nl&#x2F;code&#x2F;mu&#x2F;mu4e.html" rel="nofollow">http:&#x2F;&#x2F;www.djcbsoftware.nl&#x2F;code&#x2F;mu&#x2F;mu4e.html</a><p>[1] <a href="https:&#x2F;&#x2F;www.mailpile.is&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.mailpile.is&#x2F;</a><p>[2] <a href="http:&#x2F;&#x2F;www.claws-mail.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.claws-mail.org&#x2F;</a>
