<h4>Personal Notes</h4>

<p>To enable verification of the GPG signature from the keyservers when 
reading an e-mail, make sure that the ~/.gnupg/gpg.conf file contains these lines:</p>
<code>keyserver hkps://hkps.pool.sks-keyservers.net
keyserver-options auto-key-retrieve
</code>

<p>I use msmtp to send e-mails from my Arch linux laptop. In msmtprc,
</p> 
<code>tls_trust_file /etc/ssl/certs/ca-certificates.crt</code> 
<p>doesn't work for me, instead I use</p>
<code>tls_fingerprint</code></pre>
<p>To obtain the fingerprint :</p>
<code>msmtp --serverinfo --tls --tls-certcheck=off --host=host.domain.tld 
      --port=587 | egrep -o "([0-9A-Za-z]{2}:){31}[0-9A-Za-z]{2}"
</code>
<p>I have a cron job that updates the fingerprint regularily.</p>
<code>#!/bin/bash
# update tls_fingerprint entry in ~/.msmtprc

cd $HOME

# get the server fingerprint
KEY=$(msmtp --serverinfo --tls --tls-certcheck=off --host=mail.domain.tld --port=587 | grep -E -o "([0-9A-Za-z]{2}:){31}[0-9A-Za-z]{2}")

# replace tls_fingerprint line in .msmtprc 
sed -i "s/^tls_fingerprint.*/tls_fingerprint $KEY/g" .msmtprc
</code>

<p>
I use Chawan (cha) in my mailcap to convert html mail to text, otherwise xdg-desktop for the default applications
(see mailcap above)
