You&#x27;re right about it being irrelevant to security.  Somewhere else in this thread i pointed out that this isn&#x27;t a motivation for me, so i agree with you there.  The only reason i bring up search speed is to rebut the assertion elsewhere in the thread that my email client is a step backwards in usability&#x2F;features.<p>For me, the advantages are: works all over (<i>e.g.</i>, i can find out my buddy&#x27;s apartment address from an email in 2008 even if i&#x27;m nowhere near wifi), it&#x27;s snappy, keyboard-driven (like, really -- Google Mail with their cute mnemonics or Thunderbird with shortcuts don&#x27;t count), text-only (because i&#x27;m a nerd, and perhaps you could argue vague hand-wavey security stuff here), and because i can Elisp my way out of sticky situations. Especially the Elisp.<p>On that last point, you might well contend that if i used an email client to your liking i wouldn&#x27;t <i>need</i> to Elisp my way out of anything, but i think that&#x27;s beside the point.  For the first time in years (i&#x27;ve been using mu4e for a year now, and before that mutt, starting 2006) i&#x27;ve actually been able to make my client do <i>exactly</i> what i want using a real programming language -- certain formatting hacks, PGP to certain people in certain circumstances, email address completion the way i want it, <i>etc.</i><p>But anyway, it&#x27;s probably not for everyone :).  There&#x27;s also no such thing as a &quot;best&quot; email client, probably -- i&#x27;m just partial to the create-your-own-MUA kit that i&#x27;ve found in mu4e :).<p>This is <i>waaaay</i> off-topic though, i&#x27;m not even talking about mutt any more.  Sorry, i got a little carried away :).
